yes, so you got the same gain with stock exhaust manifold and bigger carb. that is my point from my other post that headers under 4K rpms make no difference. port work, cam and raising compression via shaved head I think make much more diffference. i have run few different cam grinds and any grind designed for modern fuel is a massive improvement as the stock cams are designed for 70 octane.
