i beleive it... "!!i cant beleive it!!!!!" also. its obvious to be a major problem. i just wondered if there is another point in the engine where the water/oil are capable of mixing because of the new heads/gaskets, ill be tearing it apart soon. who knows how long it will be before i can afford to fix it.... its been on blocks since i started the rebuild last january ( i was really looking forward to racing this spring. got a set of slicks sitting in my living room now. guess ill use the money i was going to buy the rims with on head work. sure hope its just the gasket. the heads are brand new @ $550 each. what a bad way to end a long year of building this thing. i have a victor jr intake i was planning on putting on there as soon as i get a holly to fit it. guess it will be a good time to do it all at once. i didnt want to run that performer/quadrajunk combo anyway, *temp fix untill i can get a holly. is there a way to pressure test the block/heads, like if i take it to the local shop for a "diagnosis" i want this motor strong, as i have nitrous to put on it when i switch intakes. it held up great before i switched the heads/cam. was very strong, even with the small amount of smoke from the valve seals. one more question. it has headers, into a y pipe, then straight pipe (2.5) back into duals with no mufflers in the rear. untill recently i put a flowmaster exhaust on the back end of it. that back pressure shouldnt be too much for ported heads (215cc with 64cc chambers and flat top pistons) would that have any effect on the head gaskets? or on anything else for that matter? this cam profile doesnt like to idle below say 1100 or 1200rpm. maybe i was better off without the muffler? it was extremely loud though, now its almost tolerable more of a rumble. i have made so many changes at the same time, its hard to narrow down, but i think if i can get this oil/water issue fixed, i will have a great start on a mean machine.
