4.200 MLS Head Gasket .051 - SBF

The Cometic Gaskets 4.200 MLS Head Gasket .051 – SBF is designed specifically for small-block Ford engine builders and performance enthusiasts who demand reliable, precision-fit cylinder head sealing. This multi-layer steel (MLS) gasket is ideal for engines with a 4.200-inch bore diameter and a compressed thickness of .051 inches, making it suitable for stock displacement rebuilds, street engines, and moderate-boost applications.

Constructed with layered steel and elastomer facings, this gasket provides a superior seal across varying surface finishes and head bolt pressures, offering a significant advantage over traditional solid-copper or composite designs. The .051-inch compressed thickness is engineered to maintain proper deck height and combustion chamber volume, which are critical for optimizing compression ratio and engine tuning parameters.

This head gasket is compatible with various small-block Ford engine displacements, including 289, 302, 347, and 408 cubic inches, making it an excellent choice for both naturally aspirated and lightly supercharged applications. With Cometic's precise manufacturing tolerances, users can expect consistent clamp load distribution, preventing gasket failure or coolant leakage in high-RPM environments.
