Manifold fitment question

That is why you never mill an intake manifold! Always do both sides of the heads.

The problem is you can only mill so much off the face of the head before you get into the valve cover bolts.

And, those heads only work with that intake and block.

So in the long run, it doesn't matter which you mill. Because once you start working on it, the stuff usually won't fit other things.
