This high-performance gasket features a 4.380-inch bore diameter and .060-inch compressed thickness, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • .060-inch compressed thickness allows for precise compression ratio tuning
  • 4.380-inch bore diameter optimized for Pontiac V8 engines
  • Accommodates increased cylinder pressures from performance builds, forced induction, and nitrous applications
