M50/M52/S50/S52 Cutring Head Gaskets

Proven Performance. Ultimate Sealing.

This is our recommended head gasket for forced induction applications, designed to handle extreme boost and power levels.

Key Features:

• Cut-Ring Technology – Multi-piece design with stainless cut-rings that mechanically seal each combustion chamber, ensuring superior sealing under high boost.
• No Special Machining Required – Unlike fire rings or o-ring setups, these gaskets drop in without additional machine work, making installation straightforward.
• Battle-Tested Durability – We have personally tested these gaskets beyond 1000whp and 50psi of boost, proving their reliability in extreme applications.
• Optimized Fitment – Available in multiple bore sizes, with a slightly oversized option recommended for easier installation. While a perfect bore match is preferred, a small oversize helps simplify the process for hobbyists.

Bore Size Reference:

• M52 Stock Bore: 84mm
• S50 Stock Bore: 86mm
• S52 Stock Bore: 86.4mm
  • We recommend the 87mm Gasket for easy install. For s50 86mm gaskets are available but not recommended as it is very hard to get installed correctly.
