The Cometic .060in AFM valley gasket set for GM SB2.2 Small Block V8 is made for .970in water holes and provides a compressible seal in the engine valley to prevent coolant and oil migration. It supports stable head-to-block mating while preserving clamped surface contact. AFM construction pairs nitrile foam with an aluminum core for about 85% recovery, resists temperatures above 205°F, does not require sealants, and includes embossed outer layers coated with Viton for added heat and corrosion resistance.
