I won't even fuss with factory heads anymore unless I'm doing a factory correct restoration. I don't think you can really go all that wrong with any of the entry level/factory replacement type aftermarket heads. Just figure out what you want to achieve with the engine and buy the appropriate set of heads and while your at it an appropriate camshaft as well. Just remember unless you want to swap out other parts down the line stay on the conservative side for heads and cam.
