Cyl head question

[Santeeford]

Hey guys. Im in the process of building a motor for my 93 GT. Its going to be bored .30 over with an explorer Gt40 intake and 70 mm throttle body with 76mm Mass air and 24lb injectors. Im not sure on with Head, cam, and rockers to use that will make decent power and not completely kill my wallet and will still be 50 state legal. Any input would be cool. Thanks guys
