Product Details

The Cometic C5755-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket specifically designed for Buick Big Block V8 engines. This precision-engineered gasket features a .030" compressed thickness and accommodates a 4.400" bore diameter, making it ideal for performance builds and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .030" compressed thickness for precise compression ratio tuning
  • 4.400" bore diameter designed for Buick Big Block V8 engines
  • Accommodates higher cylinder pressures than conventional gaskets
  • Excellent for turbocharged, supercharged, and high-compression applications
  • Embossed stainless steel construction with Viton rubber sealing beads
  • Resists blowout and maintains seal integrity under extreme conditions

Cometic MLS gaskets are the professional's choice for engine builds requiring maximum reliability. The multi-layer design distributes clamping pressure evenly while allowing for slight deck surface imperfections and thermal expansion. Proper surface preparation (RA finish of 50-60 recommended) and torque specifications are essential for optimal performance.
