Holden / Nissan RB30, 87mm Bore, 1.0mm Thick” Vulcan Cut-Ring”
CR330153


A hybrid design forged to harness the best sealing properties of two head gasket types:
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 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
