The Cometic .060in AFM valley gasket set for GM SB2.2 Small Block V8 fits .750in and .625in water hole configurations and seals the engine valley to control coolant flow. This valley gasket balances compressibility with sealing strength for durable pump and head-to-block interfaces. AFM construction pairs nitrile foam with an aluminum core for about 85% recovery and temperature resistance above 205°F; the outer layers are embossed and coated with Viton for added corrosion and heat resistance.
