Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8, .060in thickness with a 4.200in bore. HP shim technology concentrates clamp load at the combustion sealing area to improve head sealing on open-deck blocks. Multiple embossed stainless steel layers combine AMP coating and Viton on the outer faces while an uncoated shim layer manages thickness requirements and helps conform load distribution without excessive clamp load.
