I got a question. If you port the plastic intake to make it match the gasket, will that make the intake not seal right to the heads. I have a really bad vacuum leak now. Just wondering if that is what it is from?
The intake port on the head is quite a bit smaller than the gasket, so why would you want to flare the intake manifold out that far? Anyway, it shouldn't cause it to not seal as you would still be inside the embedded rubber sealing ring in the gasket.
