Optimise your engine's breathing and prevent gasket failure with this heavy-duty competition manifold gasket. Engineered specifically for large-bore exhaust systems, it is built to survive the extreme temperatures of high-performance A-Series racing engines.

Product Specs

• Part Number: JA441
• Type: Competition Spec / Heavy-Duty
• Compatibility: All BMC A-Series engines (850, 998, 1098, and 1275cc)
• Design: Large-bore ports to match performance intake and exhaust headers
• Application: Classic Mini, MG Midget, AH Sprite, Morris Minor

Why Choose This Competition Gasket?

• High-Temperature Reliability: Advanced material construction prevents "blow-outs" common with standard gaskets on tuned engines.
• Unrestricted Flow: Large-bore porting ensures the gasket doesn't overlap the manifold runners, eliminating turbulence and back-pressure.
• Reinforced Core: Provides a superior seal on high-compression race engines where exhaust pressures are significantly higher.
• Direct Fit: Designed to align perfectly with standard 1275 studs and performance LCB (Long Centre Branch) manifolds.

Installation Tip: For the best seal on a race manifold, ensure all mating surfaces are perfectly flat. We recommend checking the torque on your manifold nuts after the first heat cycle to compensate for initial gasket compression.
