What is better?

1. Take bigport head, skim it as necessary clear hotspots.

or

2. Take this already-pretty-skimmed-now-32cc-per-chamber smallport head find a way to enlarge chamber to 34+ cc (hotspots, sink/deshroud valves), maybe even go with 1.5mm HG

In both cases, i wouldn't like to pass 12:1 CR mark. If that ain't possible with smallport head, than bigport is only choice.

Why i keep insisting on smallport? It should be better choice for 150-200 hp and have better low/mid range. Beside cams are already seated in it.
Since Piper market this cams as Rally with power band in 3000-8000 rpm it seems smallport is better in all aspects.
