273 commando with carter afb 9510s

OK,
The idiot who owned my car before me decided that in order to save the valves he re-jetted the carb a couple of jets rich.

So I guess sacrificing the cylinder walls was a better thing.

Does anyone know what metering rods and jets I need to put the car back to stock.

Or better yet, what setup would be optimal for better performance.

Supposedly the engine has a 3/4 race cam in it, stock dual exhaust (cherry bombs) and an offy dual plane intake.

And I am in Florida.

I am also thinking about going to an Carter AFB 600cfm vac secondary carburetor, just for a little better performance.

Thanks
