the 230 thirty heads will flow a ton of air and fuel, just like vinny said good mid to upper range,
however my opinion is where do you want your engine to perform?
.200 dome pistons at 64cc heads depending on head gasket thickness your going to have high compression, and you throw a big cam into the mix its going to mean low vacuum situations which will require higher rpms to develop the vacuum needed to pull proper air and fuel.
so I would look at what your springs are rated for at maximum lift, go .100 under that for coil bind.

111163-08 NA 287 293 255 261 .600 .620 108 104 .022 .022
3800-7800 Good mid-range power, rough idle. Needs 11.0:1 CR-up. Brackets.
something like this is a place to start.The heads,unless ported are the weak link si probably a Victor jr.
the 4.10 gears are like highway gears for 1/8th mile
