318 Build Carb Tune Questions

Fishy. The head gaskets I planned on using are .039 felpro's.

Trans is a 904 w/tf2. Gears are 3.55 and converter is a 2200-2500 stall.
The headers are the partial fenderwell 5208's for early A.

Thanks cracked I was actually wondering where to start with the timing as well.
