Superior Sealing for High-Performance B-Series

The Cometic 81mm .040in MLS Head Gasket is the premier choice for Honda and Acura B-Series engine builders who demand reliability. Engineered to handle the increased cylinder pressures of high-output and forced induction engines, this multi-layer steel gasket provides a consistent, leak-free seal. The .040in thickness is a popular choice for fine-tuning compression ratios during engine assembly.

Why Choose Cometic MLS?

• Advanced Construction: Multiple layers of stainless steel provide exceptional strength and resilience.
• Viton Coating: Both sides are coated in high-temperature Viton rubber to ensure a perfect seal on imperfect deck surfaces.
