No offence but you shouldn't be giving advice lol. Rings expand when warm this is elementary mechanics, and yea the seals would blow had there been any pressure built up over 10psi or so but we could not even get a single pound of pressure to build. We tried filling it with cigarette smoke before pressurizing to try and help locate it but no dice. Even if it jumped one tooth on any of the cams ans still ran fine I would think compression would be slightly lower on one head. We got consistent 145-150 on all of them.. thanks for the replys guys I guess we will keep hunting for the leak..
