Details

Edelbrock E-Series Cylinder Head Bolt Kit #85812 is a high-quality replacement set of bolts with washers for use with Chevy W-series big-block 348/409 engines equipped with Performer RPM #60815 and #60819 aluminum heads. This kit contains all necessary bolts and washers to replace the factory bolts for a pair of heads. E-Series bolts have a yield tensile strength of 190,000 PSI for strong and reliable loading with generous filleting throughout to eliminate stress risers. 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.
