Vulcan Cut-Ring Head Gasket Suit Mitsubishi 4G63 3.398" (86.30mm) Bore x .051" Thick

New SCE Vulcan Cut-Ring head gaskets are designed for use in engines with high static compression forced-induction or nitrous oxide where typical composite or MLS head gaskets may be prone to leak combustion pressure and-or coolant. The New Vulcan Cut-Ring head gaskets are a hybrid-design which combines sealing properties of 2 different headgasket material types; Composite - a pliable, perforated metal-core composite gasket body for effective sealing of coolant and oil, without additional sealants. The stainless steel,solid stainless cut-rings biteinto the cylinder head under clamp load to form a positive barrier against combustion pressure leaks, without additional machining.

Designed for use with high static compression or forced-induction engines whichare prone to combustion pressure leaks when using typical composite or MLS head gaskets. Especially 4-bolt-per-cylinder patterns such as BMW, Subaru, Toyota and Chevrolet LS series.

Composite: Pliable, perforated metal-core composite gasket body eliminates coolant and oil leaks. No sealant needed!

Stainless Steel: Solid stainless cut-ring 'bites' into the cylinder headforming a positive barrier against combustion pressure leaks. No machining required!

EngineSealing Capability Exceeds:

• 16:1 Static Compression Ratio
• 35 lbs. Supercharged or Turbocharged forced induction
• 250 Shot of Nitrous Oxide
