19 psi = boom
 

well not really but i managed to push the head gaskets out :(

what type of gasket was it, must of been crap

stock replacement.tell ya the truth it help up kinda well.i didnt think it would make it past 12 psi,im gonna goto copper gaskets now specially since im swaping out to an aluminum 3400 top end.nice 50 cfm flow upgrade in those heads alone stock over my ported iron heads prolly pick up a total of 80+ cfm once those are ported

nope to much work to install the copper gaskets.so gonna try a felpro set or see if i can find some mls gaskets for the motor for now
