Are you sure the head gasket is sealing? If the heads have been angle milled, or sometimes after conventional flat milling, the head will not be flat at the top of the deck where the gasket has to seal the crankcase.

It would be the flat surface of the head that mates to the surface of the lower left in this image where the deck transitions into the china wall.

A feeler gauge might work to check that.
