M20 Cut Ring Head Gasket

Athena-SCE Vulcan Cut-Ring cylinder head gaskets are hybrids forged to harness the best sealing properties of two head gasket types — composite and stainless steel. With no sealant needed, the pliable, perforated metal-core composite bodies eliminate coolant and oil leaks, while the solid stainless steel cut-rings bite into the cylinder head forming a positive barrier against combustion pressure leaks — without machining.

Athena-SCE Vulcan Cut-Ring head gaskets are designed for use with high compression or forced-induction engines, which are prone to combustion pressure leaks when using typical composite or MLS head gaskets.

Bore: 85.5mm.
Compressed Thickness: 2.0mm.
