318 with a 4.00 stroke crank

The problem that I see with this has nothing to do with bobweight and everything to do with flow. I think, should this really get looked at, that notching the bores and possibly offestting the heads to clear the valve shrouding issue should be done. a 3.94 bore putis the intake .045" closer to the wall and that is huge on a 2.02 or 2.05 valve.
