What I did with my 289 mustang is have the heads machined to acommodate 1.94 intakes and 1.60 exhaust,
Ping G25 Sale, installed screw in type rocker studs and brass valve guides and port the intake and exhaust ports myself with a die grinder. Look for a head with 2.02 intakes already in it at a cost you are comfortable with. You will have to take what you can get for the best price.
