Edelbrock Chrysler E-Street / Performance RPM Head Bolt Kit

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.

E-Series Cylinder Head Bolts have a durable black oxide finish with sealer and come with the distinctive Edelbrock E stamped into the head.
