This .060" nominal gasket with a 4.530" bore installs with four bolts in the lifter valley and requires no sealants. Embossed stainless outer layers coated with Viton resist harsh conditions while an uncoated stainless shim layer enables thickness control and improved distribution of sealing loads to reduce distortion.
