This precision gasket features a compressed thickness of .036 inches and is designed for a 4.310-inch bore size, making it ideal for performance engine builds and rebuilds.

Key Features:

• Multi-layer steel construction provides superior sealing and durability under high compression and extreme temperatures
• 4.310-inch bore diameter accommodates standard and many overbore applications
• .036-inch compressed thickness allows for precise compression ratio tuning
• Undersized water ports designed specifically for aftermarket cylinder heads, allowing custom port matching and coolant flow optimization
• Compatible with Chevrolet Mark-IV, Gen-V, and Gen-VI Big Block V8 engines

Cometic's MLS gasket technology uses multiple layers of stainless steel with elastomeric coatings to ensure maximum sealing capability while accommodating thermal expansion and cylinder bore distortion. The undersized water ports give engine builders the flexibility to customize coolant passages to match their specific aftermarket heads, preventing potential sealing issues from mismatched port configurations.
