We are now stocking the AllPontiac Cometic head gasket for the IA II and stock Pontiac blocks of all sizes. From 4.150 to 4.410 bore. They can be used over 5 times. This will be a big cost savings for the NOS and Blower motors. No O-rings needed for this gasket.

''The larger bore design has the stronger "round" fire ring and center layer embossing. The latest consensus is that the Cometics will take everything any copper and o-ring will."
