Product Details

The Cometic C5274-040 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This gasket features a .040" compressed thickness and is designed to accommodate a 4.135" bore diameter, making it ideal for performance builds and applications using Edelbrock RPM cylinder heads.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
  • .040" compressed thickness allows for precise compression ratio tuning
  • 4.135" bore size accommodates stroker and oversized bore applications
  • Specifically designed for compatibility with Edelbrock RPM aftermarket heads
  • Embossed stainless steel layers with advanced coating technology resist corrosion and micro-leakage
  • Eliminates the need for sealants or re-torquing after installation

Cometic MLS gaskets are the choice of professional engine builders and racers worldwide, offering exceptional reliability in street performance, drag racing, road racing, and marine applications. The multi-layer design allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping pressure across the entire sealing surface.
