intake milling

Man all that thinking is making my head hurt. I had the same problem on my 340 build. The block was decked 0.020 and the heads were cut from 72cc to 65cc. The machinst (a chevy guy) said we won't need to cut the intake side of the heads. Well guess who was wrong because the intake wouldn't begin to bolt down. So off came the heads for intake side milling.
