• Compressed operating thickness of 0.036 inches, optimized for precise sealing and durability
• Embossed outer layers that improve gasket-to-surface contact and sealing integrity
• Center shim layer of uncoated stainless steel, customizable for varying thickness requirements
• Designed to resist corrosion and rebound from shearing forces between dissimilar metals (aluminum heads to cast iron blocks)
• Compatible with World Products Man-o-War blocks and other high-performance engine builds
• No sealants required, simplifying installation and reducing potential leak points
• Specifically engineered for Chrysler 6.1L Gen-3 Hemi engines with a 4.125-inch bore and aluminum sleeved blocks

Construction & Design:

The gasket’s multi-layer steel design combines durability with flexibility, allowing it to maintain a tight seal under extreme operating conditions. The stainless steel layers provide structural integrity and resistance to corrosion, while the embossed outer layers coated with Viton rubber ensure a reliable seal against combustion pressures and thermal expansion.

Viton, a high-performance fluoroelastomer, is chosen for its exceptional heat resistance and chemical stability, making it ideal for the harsh environment inside the combustion chamber. The gasket’s 0.036-inch compressed thickness balances sealing capability with the necessary compliance to accommodate engine block and head surface variations.
