Carb question

[rustynutz45]

Hello new to the board and wondering what is a good place to start for jet size in a Holley 5200 carb on a mustang 2.3...our rules are pretty stock with the exception of a .442 lift cam and a bore of .40 over. Head must be completely stock. We run on asphalt if that matters. Thanks...
