... with no headers and stock compression you're probably not making more than 250-300. A 9.5 motor with decent exhaust would probalby make 350.

oh, those are pretty good heads, I would say not less than 325, maybe even 350, again, depending on CR.

It won't be overkill but I doubt you will notice any gain with the carb change.

500-600 HP, not more than 5500-6000. R's are more what kills it, the rods stretch and break.
