Silicone / Metal Valve Cover Gaskets - Valve Cover Gasket Fits All Small Block Chevy- Sold in Pairs
Hardin Marine's Perm-Align valve cover gaskets are specially designed for
that hard driving, all-out racer who wants to be sure that he has the best
protection against valve cover leakage caused by the valve cover gasket being
blown out or sucked in by changes in internal engine pressures. The gasket is
made of 30 durometer rubber vulcanized to both sides of a thin steel frame and
will far outlast cork and rubber composite gaskets. They can be used many times.
