If I follow your thinking here, and I think I am, it seems to me the exhaust would benefit the most. Funky chamber, shrouded valve. The exhaust has always been horrific in terms of flow and efficiency, made more challenging by the two end ports as singles and the center ports As siameased. So the wider lifter May support a quicker ramp and a longer duration on the exhaust side. Very interesting. A flow bench, cam grinding machine, and a dyno would come in handy right about now.
