Flathead Re-builders....Do You

[rockfla]

Question of the day?


Had a head gasket let go on a sort of "tired", good running flathead (pushing coolant out the back of the head). Pulled the heads and no evidence of any cracks. Having the heads checked now and IF good having them "decked". The question is.......Since the block is not getting decked......do you use any kind of "sealant" product around the water ports on the block and heads with the newer graphite head gaskets???
