Edelbrock E-Series Cylinder Head Bolt Kit #85562 is designed for use on Pontiac engines with Edelbrock Performer and Performer RPM Cylinder Heads #6056-6058. Note that this head bolt kit is required to install these Edelbrock Pontiac heads. The 6056-6058 cylinder heads require a head bolt kit that is similar to that needed for a Ram-Air IV head, which is different from a standard D-port head. Several of the bolt boss heights have been increased to enhance the potential of the heads. E-Series bolts have a yield tensile strength of 190,000 PSI for strong and reliable loading. Bolt threads are rolled after heat-treating for superior form and strength, while a small hex head provides extra space for socket clearance in tight situations. E-Series Cylinder Head Bolts have a durable black oxide finish with sealer and come with the distinctive Edelbrock “E” stamped into the head.
• For use with Performer/Performer RPM heads for Pontiac.
• Yield tensile strength of 190,000 PSI.
• Heat treating with rolled threads for superior form and strength; black-oxide finish with sealer.
• Edelbrock “E” logo stamped on bolt head.

Coat threads, washers, and underside of bolt heads with motor oil for accurate torque readings.; Torque upper row of bolts to 105 ft. /lbs., torque lower row of bolts to 95 ft./lbs. in three even increments. Start in center and work out towards ends. A re-torque is recommended after initial start-up and cool-down (allow 2-3 hours for adequate cooling).
