There are always better cams for any given combo,but you gotta ask yourself if you are willing to potentially spend big $$$ on buying multiple cams to try on the dyno to chase after what may amount to minimal gains.

And as I understand it,the Eheads max out @ 340-350 or so CFM before going to a wide port configuration,so there may a minimal gain there too,but again one has to ask themselves if it would be worth the trouble to do such.

CR is the real challenge,agree you may be maxed out there to still run it on pump gas.

Tell us about the rest of it,intake & exhaust tracts,rocker ratios and the like.

Might be something there to be had.

Honestly,the dyno time alone to do something like this properly would be pricey.

IMO there's always something more to be found if you look hard enough,but it's a matter of ROI in terms of both time & $$$$.

FWIW
