Been awhile since Ive posted here but Ive recently just got back in the game. What are you guys doing to seal up 45lbs of boost on a conventional head big block Chevy? Block is solid Brodix 4.500 short deck deal. Heads are solid Brodix BB-3. Blower is an older Kobelco turning 32 over. I keep having issues pushing head gaskets around 42lbs. Usually 2 and 4 fire slot and kaboom. Ive heard about using AJ fire rings or hoops to hold big boost but wanted to get feedback here if anybody has ever used them?
