Default Ported LS2 head enough?

2005 GTO with stock heads, SW LT's, Magnaflow and a bumpstick
measuring 235/241 .614 on 112. I am looking to just get a quality port
and valve job on the stock heads. I am looking for opinions on how much I am leaving on the table not going aftermarket with the heads.

If the port and valve job is good you will be leaving very little on the table...you may even make a little more than the aftermarket head in as shipped form.

Well I did not have the coin to do the aftermarket heads along with the other upgrades I had decided on. My cam is a Flowtech grind and I have been very happy with it so I decided to have Flowtech do the heads also. As the heads go back on I have bought a few other pieces to go on also. I am shooting for 400 to the wheels uncorrected.
