Details

Head Gaskets
The head gasket we recommend for our 23deg. heads used on 327/350/383/400 SBC engines without steam holes is Felpro #1003. On engines using the GM 400 block, or aftermarket blocks with steam holes, use Felpro #1014

Intake Gaskets
Our heads are manufactured with both the conventional intake manifold bolt pattern, and the Vortec bolt pattern. If you're installing a Vortec manifold, use Felpro #1255 gaskets. If you are using a conventional intake manifold, use Felpro #1266 gaskets

Push Rods
Our aluminum 23deg. heads typically use +.100" (longer than stock) push rods, Depending on the components used, it is 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

Spark Plugs
SBC heads use standard 14mm. x 750" reach, 5/8 hex, gasket seat spark plugs like NGK R5671A-7, Autolite 3924, Champion RC12YC, etc. Remember that higher compression/ boost require a colder heat range spark plug

Exhaust Gaskets
We recommend the use of our Exhaust gaskets # Fel-Pro #1405 on our 23 degree heads.….
