Product Details

The Cometic C15523-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 428 and 455 cubic inch V8 engines. This precision-manufactured gasket features a .051-inch compressed thickness and is designed for a 4.380-inch bore diameter.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .051-inch (1.3mm) compressed gasket thickness
  • 4.380-inch bore diameter for optimal combustion chamber sealing
  • No water hole configuration for specific engine applications
  • Designed for high-performance and racing applications
  • Eliminates gasket failure and coolant leaks common with composite gaskets

Cometic MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to provide maximum sealing performance under extreme cylinder pressures and temperatures. The no water hole design is ideal for specific Pontiac engine builds where coolant passages are routed through alternative pathways. This gasket is perfect for engine builders and enthusiasts looking to upgrade from stock gaskets in performance, racing, or high-compression Pontiac applications.

Joyce, the phone rep, was very helpful. Eager to receive the parts.

Easy to find parts and immediate shipping.

I hope it is the correct EGR VALVE for a 1992 Lexus SC 400
