Good head gasket sealer

[CamaroAdam73]

Does anybody know of/ or use a good head gasket sealer?

If it makes a difference it's a no frills stock spec 350 going into a truck, she blew the head gasket so im doing a top end. The guy bought a fel pro kit so it's probably just a standard head gasket.

If you’re using a composite head gasket, they go on clean and dry period. If it has blown a head gasket, check both the head and deck surface to make sure they are true and correct as necessary.

The only exception is when using a steel shim head gaskets, which case a thin coat of “copper coat” head gasket sealer should be sprayed on both side.
