I have overhauled the engine on my CA and wondering about putting the head gasket on "dry" or using some type of sealant. The CA service manual says to use a non-hardening gasket cement. What about using Permatex Copper Gasket Spray on the new gasket? Thanks in advance for suggestions Mike

Use a skim coat on both sides of the gasket around the outside perimeter, from the edge to 1/4" in from the edge.Also around the water holes and push rod holes both sides of the gasket.

| Check out my WC Dilema above! I would highly recommend the anerobic gasket sealer! It has excellent sealing properties and stays flexible. I used a Permatex Anerobic Gasket Sealer product, Locktite has one also, as well as the Hylomar product shown. I wouldn't install it dry...it's no fun doing it twice. |
