Description

INTAKE GASKETS:
Our heads are manufactured with both the conventional intake manifolds. PCE349.1011EXHAUST GASKETS:
We recomend the use of our Exhaust gaskets, PCE355.1001, on our 18 degree heads.PUSH RODS:
Our aluminum 18deg. heads typically use +.100" (longer than stock) pushrods. Depending on the components used, it maybe that possible that you may need pushrods shorter or longer than that so we recommend that you use an adjustable pushrod to dial in your rocker geometry and order pushrods to match.
