Why Choose the BK450?

• Superior Sealing: Engineered to handle high compression ratios and increased cylinder pressures without failing.
• Proven Versatility: Equally at home in a daily-driven 1275GT or a full-spec historic race Mini.
• Modern Technology: The composite material offers better recovery and heat dissipation than traditional copper gaskets.
• Reliability: Features reinforced fire rings to prevent "blow-outs" between cylinders—a common issue on tuned A-Series engines.

Installation Tip: To get the best out of this gasket, ensure your cylinder head and block faces are perfectly flat. We highly recommend fitting this with an ARP Head Stud Kit for maximum, even clamping force.
