Well after my cam fiasco I came up with a small port head. I am after a street engine (no more than 300HP.) and a nice off idle to midrange perforamce. Would the small port work for that?

For the most part the engine is stock with a pasesetter header and a 3" exhaust.

Thanks in advance

Small ports add velocity to the incoming air charge. This is good, if you like torque before the turbo spools. You can keep the ports small while improving efficiency by grinding any irregularity's and halving (or fully removing) the valve guides.
