Here's what I'm thinking and you tell me if this will work or if my idea is flawed. Angle mill the bottom of the head with an emphasis on the outter edge (removing more material as you get closer to the exhaust side). This will make the intake side "lay over" a little more. This would open up the distance from the tops of each cylinder heads intake face while not really affecting the bottom. (Basically widening the angle of the "V"). You would then machine the intake to match the corresponding angle of the heads. You could then use thicker or double intake gaskets to fill the resulting wider gap between the intake and heads, or deck the block to bring the heads down a bit which would not change the angle of the "V", but would reduce the gap. This would also change the chamber volume & compression ratio. This should bring the stock head / 2115 intake mating angle closer to stock. Only problem would be getting the head bolt holes back to the correct angle since the head will be laid over a bit.
