Edelbrock E-Series Cylinder Head Bolt Kit #85912 is specially designed for use with Chrysler big-block engines equipped with E-Street/Performer RPM cylinder heads (#60825, 60829, #60929, #60185, #60189, #5090 and #5093). This kit contains all necessary bolts and washers to install one set 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.
