So I’m still an infant in the GN world and I will say that they make you question and double check everything!! My situation...
I buy a used BGC intake and an early set of GN1 Aluminium champion heads. I’m mocking everything up and I sit intake down with gasket and tighten it up with a set of SS bolts that are for a champion intake. I was told that the deminsions are the exact same between a Champion intake and a BGC. The bolts are all the exact same size, “Which came from a big name vendor that I bought in person and not thru the webs”. Anyways I start all bolts by hand and just snug with a battery powered 1/4 drive. There were 3 that got tight. Didn’t think anything about it. Well after the final mock up and all looks good it’s time to disassemble to use sealer and reassemble for final time.
4 bolts don’t want to come out and 2 snap off in the cylinder heads. Nice right.. Well I measure to find out what the hell happened. I knew that I cleaned and chased all threads. Well after measuring the holes of the heads and the size of the bolts I found out that if they bottomed out there could be almost a 1/4” to much bolt and the battery tool just made those nice shiny, sharp bolts eat into the heads. So here I am.. thinking you must check every. Single thread and height on these dam engines yourself. Don’t take final words from anyone just trying to get your dollars.
It’s all my fault this happened I’m just hoping that new guys will take some advice from a guy who admits all his screw ups. Cheers!!
