which one is better hand ported or cnc ported?
it doesnt matter, it depends on who designed the cnc program or who is porting the heads by hand.....
just pick a set of heads.your car will never "haul *****" if you dont pick some heads and get them on there.

It really is a tossup, a shitty porter can make the best head flow nothing, and a good porter can make a **** head great.
But as already stated, a cnc head is more consistent. If you have access to someone of exceptional talent, use them, I do my own under the eye of a very talented porter.
If I couldn't, I would opt for a cnc head.
Aren't you spraying this motor? If so then every cfm will not break your performance, not as much as the wrong converter, gear, system, and mostly the cam.
