You're kidding right? Seriously? You didn't use the valley gaskets at all???

I know when mocking up my machined LIM and IC years ago, I place it on with just the intake gaskets and no valley gaskets and I remember there being a good gap in those areas IIRC. Granted it wasn't bolted or torqued down, I don't see those gaps closing that easily honeslty. You had to of used a **** load of RTV to seal that up.... good luck if you ever have bad vacuum problems, check there first.

Some motors don't use those valley gaskets and you use RTV in place, like some SBCs. But I'd say they are needed on a 3800 Series 2 IMO.

Not trying to get on to you or anything man, but I don't see how you made that work. All I can say is good luck.....
