I have recently purchased a 4 bolt chevy 350 decked block. I have a good set of chevy HP heads that match that I purchased seperatly. I would like to know if anyone has had problems or suggestions on what I need to do to match it up with a good Intake that will not have a gap. I am also looking for a good top end set up with roller rockers. I understand with a decked block, I will need to check valve clearence.
