Edelbrock E-Series Cylinder Head Bolt Kit #85032 is designed for use with Edelbrock Performer RPM 60049 Cylinder Heads for Buick 400/430/455 CID big-block engines, or any Buick cylinder heads with similar column heights. This kit includes a complete set of bolts for a pair of cylinder heads. These bolts are intended for cylinder heads with four head bolt columns of 1.92 height, two columns of 1.925 height which accept a 2.88 head bolt when used with a .120 washer, and four head bolt columns of 3.11 height which accept a 4.00 bolt with a .120 washer. 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.
