Thanks for the response. I checked the heads and deck using a precision straight edge and a feeler gage checking horizontally , vertically , and diagonally in multyple spots. I never thaught to check the dowl pins but im gona. I'll go look at the gaskets again just to be sure. I never had this problem before , its driving me nuts. If head chamber was cracked wouldn't i loose compresion in that cylynder? You got me thinking theirs a possible crack under the valves . I was thinking about sealing off the two water passages on the intake side, and filling heads with coolant let em sit on the head stands and see what happens.
