Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
• 4.200" bore diameter accommodates standard and slightly overbored Windsor V8 applications
• .056" compressed thickness allows for precise compression ratio tuning
• Designed for non-SVO Ford Windsor V8 engines (260, 289, 302, 351W)

• Exceeds OEM specifications for street, strip, and racing applications

Cometic MLS head gaskets are the preferred choice of professional engine builders and enthusiasts who demand maximum reliability. The multiple layers of stainless steel provide the gasket's ability to rebound and seal effectively through thermal cycling, while the precision-cut combustion chamber openings ensure accurate compression ratios. This gasket is compatible with both cast iron and aluminum cylinder heads when proper surface preparation and assembly procedures are followed.
