Gaskets & Seals

Head and intake gaskets, exhaust and header gaskets, seals, O-rings and complete gasket sets — SCE Gaskets, Edelbrock, Crown Automotive and more.

Gaskets are specified by bore and by material, and the bore is what most orders get wrong. A head gasket has to clear the cylinder without overhanging it, so an engine that has been bored oversize needs a gasket cut for the new bore rather than the factory one. Thickness matters too: it sets deck clearance and therefore compression ratio, which is why a build sheet specifies it rather than leaving it to whatever is on the shelf.

Material follows the job. Composite suits a stock rebuild and seals well on imperfect surfaces. Multi-layer steel handles boost and higher cylinder pressure but wants a flatter, better-finished deck. Solid copper is for high-output engines and generally needs O-ringing to seal reliably.

Many listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.
