intake installation dilemma

[Rapid Robert]

I did use thread sealant (the 1st time, shoulda this time). I did one bolt at a time but the alum intake is wider at that point so I had to bend it outward toward the fender & this tilted the 2nd bolt hole but tightening that bolt in that hole bent the hole flush with the bolt head so all done. thanks guys for the comprehensive info/help.

Well, that's arguable. Without sealant on the intake bolts, since they are drilled all the way through the heads and into the valve cover area, they are subject to crankcase pressure. That means oil can actually migrate up the bolt threads from the positive pressure exerted by the crankcase. It happens.

Quite doubtful
