cnc port or gasket match port tw heads?

hey guys Ive been out of the mustang game for awhile, currently I am running a cobra intake, 24lb inj, 274hr cam, tw 170's, power pipe, 80mm pro m meter, 1 3/4 lt headers. Do you guys think its worth the extra penny to get a cnc port (190 or 205) or should I gasket match port the heads? I recently ordered a holley systemax intake II as well since I know the cobra intake is choking the power a little bit. I had it dynoed when i was in high school but the combo was pretty weak, on the dynojet it made 326rwhp and 376rwtq. It consisted of cobra intake, 19lb inj, e-cam, 1 5/8 headers, chokemasters, bbk cold air, tw 170's, and thats all i could remember. Do think after installing the holley intake and porting the heads will get me close to 380-400 rwhp ? I did some research as well but only saw a few combos.
