Isn't better to buy the bare heads or buy the built heads?

Cnc heads still need to be looked over w/ a new valve job possibly correct? What about having them ported more or do the cnc flow pretty close to max?

Depends on the cam, if you plan to check them ..and if you have parts laying around to implement..what you're doing.
I'd rather buy the good parts and put it together. I don't like mystery valve springs and I prefer to use comp super locks n retainers. That's the best **** comp has besides pro magnum rockers..the cams are 3rd.
