SCE Gaskets Cylinder Head Gasket CR330069; Vulcan Cut RIng Perforated Metal-Core Composite .051" 95.00mm Bore for 1973-1976 BMW CSL 4 cyl M49

A hybrid design forged to harness the best sealing properties of two head gasket types - Composite abnd Stainless Steel. Pliable, perforated metal-core composite gasket body eliminates coolant and oil leaks. No sealant needed! Solid stainless cut-ring ‘bites’ into the cylinder head forming a positive barrier against combustion pressure leaks. No machining required! Designed for use with high static compression or forced-induction engines which are 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.

Engine Sealing Capability Exceeds:

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