with out knowing more about the engine and car and head flow?
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

well the head flow. Intake is 307cfm @.700 lift and exh 213cfm @.700 lift. I figured if i went to 4.56 or 5.30 i would be gear dead not having a stroker motor but im new to drag racing so i dont know to much.

Like I stated before,the heads flowing 307 CFM is a weak point for big power.If you are building a mild-moderate street car,those heads will work.maybe think about how fast you want to go,and how many horses it will take to get there?If the castings can be ported,that is also an option

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.
