Maybe... Why don't you pulls the heads and see. From what you said, up to temp, means up to pressure. It could be gaskets. Unless you just want new heads?...
Well the heads are off to the shop for a pressure test. Cylinder bores look good with the exception of #5 which has a pit near the top of stroke about 1/8" x 3/8". It can be felt by touch which if memory serves means it's at least .002" deep. This cylinder registered 140 PSI before pulling the heads. #3 read 145 & #7 138. Running a straight edge along the left deck checked pretty good. Couldn't get a .0015" gauge under anywhere however the right bank deck is a different story. So the question arises: just how flat does the deck need to be? Additionally is one gasket manufacturer better at accommodating out of flatness. In another world I'd be fixing the block but money is really tight and since we're in AZ I want to get back on the road.
