Re: 67 351e
Even though you had the head surfaced, you'd have to also deck the block to get a copper gasket to get a good compression seal, in my experience. It is also possible that the block is cracked. You're getting a compression leak into the cooling system, is my take. What to do? That depends on how deep your pockets are. Maybe someone knows an economical solution for you.
