INSTALLATION INSTRUCTIONS  
PLEASE study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and  
procedures. However, you should be familiar with and comfortable working on your vehicle. If you do not feel comfortable performing this installation,  
it is recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at:  
1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday or e-mail us at [email protected].  
IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation  
will void your warranty and may result in poor performance and engine or vehicle damage.  
DESCRIPTION: Edelbrock E-Tec 170 cylinder heads are designed for street/high performance use on 302, 327, 350, and 400 c.i.d. Small block  
Chevrolet engines using Vortec style manifolds. E-Tec 200 cylinder heads are high-end street and racing cylinder heads intended for large  
displacement small block Chevrolet engines. Both of these heads feature 64cc combustion chambers. Complete cylinder heads come assembled with  
valvetrain parts capable of operating up to 6500 rpm. Higher rpm applications will require the use of suitable valvetrain parts, such as larger  
valve springs and retainers. Other outstanding features include phosphor-bronze valve guides, ductile iron valve seats and premium one-piece,  
stainless steel, high-flow valves, heat-treated machined steel retainers and valve locks, rocker studs, 5/16” guide plates, and heavy duty valve springs  
which work with cams having valve lifts up to .600”. Spring load at .600” lift is 340 lbs. Check camshaft manufacturer’s spring load specifications  
when using other than Edelbrock camshafts. These powerful heads use the stock Vortec location for intake and exhaust flanges and bolt holes,  
and centerbolt valve cover rails for compatibility with original equipment and aftermarket parts. Bolt holes for exhaust and intake flanges and rocker  
studs are fitted with helicoil inserts for increased strength.  
APPLICATIONS:  
60959 (bare) / 60979 (complete) - 302, 327, 350, and 400 c.i.d. Small block Chevrolet engines using Vortec style manifolds. They also  
replace original equipment on 1996 through 1998 Vortec 5.7L equipped vehicles (C.A.R.B. E.O.  
pending. Call Edelbrock for detailed information). E-Tec 170 feature high velocity 170cc intake  
ports and 70cc exhaust ports. Complete heads feature installed 1.940” intake and 1.550” exhaust  
valves.  
60696 (bare) / 60989 (complete) - Intended for large displacement small block Chevrolet engines. E-Tec 200 cylinder heads feature  
200cc intake and 78cc exhaust ports. Complete cylinder heads include 2.020” intake and 1.600”  
exhaust valves.  
Complete cylinder heads are assembled with the following components:  
Stainless steel, one-piece, swirl-polished intake and exhaust valves with under-cut stems for increased flow  
2-ring positive oil control seals on 6097; High quality vitton lip seals with metal jacket on 6098  
Edelbrock Sure-Seat valve springs #5767  
Retainers #9724  
Valve keepers #9616 for PN 6098, #9611 for PN 6097  
Valve spring seats #5769  
5/16” pushrod guide plates, or hardened washers* for use with self-aligning rocker arms.  
*When using self-aligning rocker arms, remove guide plates and install the supplied hardened washers underneath the rocker studs.  
NOTE: Complete cylinder heads are assembled and prepared for installation right out of the box. Bare cylinder heads will have valve  
guides and seats installed, but will require final guide sizing and a valve job to match the valves you will be using.

Intake Manifold: Although stock Vortec intake manifold will fit,  
Edelbrock E-Tec 170 Cylinder Heads are matched in size and  
operating range with Edelbrock Performer, Performer RPM, and  
Performer RPM Air-Gap Intake Manifolds. Part numbers 2116, 7116  
and 7516. 7116, 7516, 2912 and 2913 are recommended for E-Tec  
200. Do not use cork or rubber end seals supplied with gaskets. Set  
the manifold on the engine with gaskets installed and measure the  
gap between the block and the manifold end seal surface. Remove  
the manifold and apply enough automotive O2 sensor-safe RTV  
silicone sealer to fill the gap along front and rear of block,  
overlapping gaskets at the four corners. Follow gasket  
manufacturer’s recommendation for the use or non-use of sealant  
for the type of intake gasket used. Install manifold and apply Loctite  
242 thread locker or equivalent to the intake manifold bolt threads  
and torque down to 11 ft./lbs. using the factory specs for torque  
sequence.  
Exhaust Headers: Any header or manifold designed for original  
equipment Vortec heads will fit Edelbrock E-Tec 170 Cylinder Heads.  
E-Tec 200 will require the use of headers suitable for Fel-Pro #1405  
(1-3/4” is minimum recommended). Exhaust ports are CNC-profiled  
to match Fel-Pro #1404 exhaust gaskets for 6097 or 1405 for 6098,  
which are recommended for these applications.  
Spark Plugs: Use 14mm x 3/4” reach gasketed spark plugs. Heat  
range may vary by application, but we recommend Champion RC-  
12YC (or equivalent) for most street-driven applications. Use anti-  
seize on the plug threads to prevent galling in the cylinder  
head, and torque to 10 ft./lbs. Do not overtighten  
sparkplugs!  
INSTALLATION PROCEDURE  
Installation is the same as for original equipment cylinder heads. Consult  
service manual for specific procedures, if necessary. For 350 c.i.d. and  
smaller engines (4.00” bore or less), we recommend Fel-Pro #7733-PT2  
head gasket for applications up to 420 HP, #17030 marine gasket for up  
to 450 HP and Fel-Pro #1003 beyond that level. Also, GM #10105117 or  
Detroit gasket #5565HG. For 400 c.i.d. or larger, Fel-Pro #8364-PT for  
moderate horsepower applications, and #1014 for high power  
applications. Also, GM #10159455 or Detroit gasket #55431HG. In any  
case, for 400 c.i.d. applications, steam holes must be drilled in  
cylinder heads as shown in Fig. 2. Be sure that the surface of the  
block and the surface of the head are thoroughly cleaned to remove any  
oily film before installation. Use alcohol or lacquer thinner on a lint-free  
rag to clean. Apply Teflon pipe sealant or suitable sealer to head bolt  
threads. Apply 30W oil or suitable lubricant under side of bolt heads and  
washers. Torque to 65 ft./lbs. in three steps (40, 55, 65) following the  
factory tightening sequence (see Figure 1). A re-torque is recommended  
after initial start-up and cool-down (allow 2-3 hours for adequate  
cooling).  
Figure 1 - SBC Cylinder Head Bolt Torque Sequence  
Torque Bolts to 65 ft./lbs.  
(Torque in 3 steps, gradually approaching final torque spec.)  
Fig. 2 - Steam Hole Location for 400 c.i.d. engines only  
Drill three 0.125” holes in each head using 400 c.i.d. head gasket as a  
guide. Drill only the three lower steam holes (closest to the spark  
plugs) as indicated in Fig. 2. Drill straight into the head (90º to the  
deck) until drilling breaks through into water jacket (about 5/8”).  
COOLANT STEAM HOLES ABSOLUTELY MUST NOT OVERLAP INTO  
THE HEAD GASKET SEALING RING (FIRE RING) AREA.  
SPECIAL INSTRUCTIONS FOR E-TEC ALUMINUM CYLINDER HEADS #60979 & #60989  
Complete E-Tec cylinder heads #60979 and #60989 are sold with the pushrod guide plates and rocker studs installed, but they will require checking  
for proper valve train and pushrod clearance before operating engine.  
PUSHROD GUIDE PLATE ALIGNMENT: The pushrod guide plates are attached to the cylinder heads with two (each) rocker studs. There is enough  
clearance around the stud holes to adjust the guide plates for optimum alignment of your valve train components.  
1. After the heads have been bolted on your engine and torqued to specs, install your pushrods, rocker arms, and rocker arm adjusting  
nuts.

2. Check pushrod-to-cylinder head clearance. YOU MUST CHECK TO ENSURE THAT THERE IS CLEARANCE BETWEEN THE PUSHRODS  
AND THE CYLINDER HEADS (.005” minimum).  
3. If adequate clearance exists between the pushrod and head, slowly turn engine through at least two revolutions while watching pushrod.  
Make sure that pushrod does not rub on the head either at full lift or when the valve is seated.  
4. If pushrod rubs on the cylinder head, remove rocker arms, loosen the rocker studs and move the guide plate as needed to provide  
clearance.  
5. After checking all pushrods for proper clearance, ensure that the tip of the rocker arm is making adequate contact with the top of the  
valve stem.  
6. Carefully re-torque to 45 ft./lbs. any rocker studs that were loosened. Check alignment again to be sure that the guide plates did not  
move while torquing the studs.
