SPECIAL INSTRUCTIONS

FOR E-TEC ALUMINUM CYLINDER HEADS #6097 & #6098

Complete E-Tec cylinder heads #6097 and #6098 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” min.).

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.
