That being said, I have SR heads on my car and they work well but they are at their limit of what can be done with them. On this motor 4.250X3.9 I could use some more intake volume. We moved the pushrods, run T&D offset rockers, and set the intake port volume at 260 cc. No use trying to go any bigger than that as you can't support any bigger port with the valve limitation on those heads. Peak intake flow at .750 lift 345ish
