Product Description

Reher-Morrison Valley Head Lug Kit

This kit was developed to help eliminate the lack of clamping force between the deck of the block and the cylinder heads on cylinder #’s: 2,3,6 & 7, on Mark IV through Mark VI Big Block Chevrolet engines. This problem can be significant on engines with more than 11.5 to 1 compression and in all racing applications.

Installing this kit provides the “missing head bolts” to this outstanding engine series, which work in conjunction with most high performance heads available in the marketplace today. Once installed, it eliminates the problems of blowing out the head gaskets between the intake and these cylinders. It will allow your engine to contain higher cylinder pressures and deliver more of the power potential it offers.
