Engine rebuild

I have just started stripping my Li 125 engine rady for a rebuild. I am starting a shopping list for all new bearings etc, would the following setup be ok for a mild upgrade from standard and to give me a good base to improve things as money allows.
Mec GP race crank 58mm Stoke, 107mm conrod
175 conversion kit (would alloy or iron head be better option)
Electronic ignition
42mm ancillotti clubman
What carb would you recommend.
