The Cometic C5551-036 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This premium gasket features Cometic's MLX (Multi-Layer Stopper) technology, combining multiple layers of stainless steel with advanced stopper layer design to maximize sealing pressure around the combustion chamber.

Key Specifications:

  • Bore Size: 4.220 inches (suitable for stroker and overbored applications)
  • Compressed Thickness: .036 inches
  • Round bore design for optimal combustion chamber sealing
  • Compatible with all aftermarket aluminum cylinder heads
  • MLX Multi-Layer Stopper construction

Performance Features:

  • Multiple layers of stainless steel provide superior strength and heat resistance
  • Stopper layer concentrates sealing pressure around cylinders to prevent head lift
  • Viton rubber coating ensures excellent oil and coolant sealing

  • Withstands extreme cylinder pressures and temperatures

Cometic MLS gaskets are the choice of professional engine builders and racers worldwide. The .036" thickness allows for precise compression ratio tuning, while the 4.220" bore accommodates engine displacements up to and exceeding 400 cubic inches. This gasket is designed for use with aftermarket Pro Heads and other performance aluminum cylinder heads on Gen-1 Small Block Chevy engines (262-400ci).

easy

1st order with Autoplicity very easy process, good price and fast shipping. I will be back for sure.

Awesome!

Great prices and great communication!!

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.

Very easy to find what I needed great job

Cheap price
