before we can reccomend what you need we need to know what jets are in there now. that will be the most accurate way to do it. as for your mods it sounds like youre going to need to be runnin some higher octane fuel for the timing and compression increase. have you thought about that yet? id say wait till you get your parts, tear the carbs apart and see whats in there. then we can get you jetted propertly without you having to spend a ton of money on jets..
