M20 Cut Ring Head Gasket

The gasket we spec for every high horsepower boosted M20 build at BimmerHeads.

Athena-SCE Vulcan Cut-Ring gaskets are a hybrid design — combining a pliable, perforated metal-core composite body with solid stainless steel cut-rings that bite into the head and form a positive seal against combustion pressure. No sealant required.

Engineered for forced-induction engines where standard composite or MLS gaskets fall short.

Pair with our M20 ARP head stud kit for a complete boosted head sealing solution.
