I have to wonder what the costs are in having intakes for both heads models and those port matched for each, not to mention dyno time.

I too was hoping for direct comparisons but, it does seem costly.

Just my thoughts.

Perhaps the best comparison at this point would be the trick flow Intake with the same Carb / spacer set up he used on the 240 engine.
We know the difference the dry dump/ compression made, thus we can extrapolate from that point- perhaps?
