ARP SEALER IS juNK ANY THING But THAT STUFF oil base and will wash off bolts/studs.the only heads studs i had leak was ones i used that crap. love there fasteners hate there sealer.when you cut the 030 off you must of recut the O rings if not that is one thing that going never be right . one thing to look at are the block front and back wall s that close in the lifter valley we call them china walls came from...the great wall of china.. if the intake hit on bottom of the block it will look like the gasket are sealing but stopping the intake sealing on the heads
