PCE has already done the work for you; our Top-End engine kits will save you the time and hassle of mixing and matching components yourself. These kits are specifically designed to deliver the performance you want, at a better price than purchasing the parts separately.
Cylinder Heads Suggested Parts 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 PCE PCE348.1006 or Felpro #1014. Push Rods Our aluminum 23deg. 100 (longer than stock) pushrods, 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 All PCE 23deg. SBC heads use standard 14mm. X 750 reach, 5/8 hex, gasket seat sparkplugs like NGK R5671A-7, Autolite 3924, Champion RC12YC, etc. Remember that higher compression/ boost require a colder heat range sparkplug.
