Edelbrock E-Series Cylinder Head Bolt Kit #85522 for Ford small-block engines

Edelbrock E-Series Cylinder Head Bolt Kit #85522 is a high-quality set of bolts for use on Ford 289-302 blocks with standard 7/16-inch head bolt bosses. This E-Series kit is a perfect choice when upgrading to Edelbrock Performer or Performer RPM Cylinder Heads. This kit includes step-washers for use with aftermarket aluminum heads using _-inch head bolt holes. 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 ÒEÓ stamped into the head.
