Cam question
I have stock LS6 243s, Cometic .040, kooks with hi-flow cats 3" to the back, LS6 intake, with a TSP228R 114LSA 405RWHP 373RWTQ.
How much will I gain with a TSP V2 233/239 on 112LSA .598 and .603 lift?

I have a ported FAST intake with milled and ported 243's from Cartek with a 228-232 582/598 lift cam and I made 453 and 400. Im thinking of swapping the heads to a nice set of milled and ported Trickflows for that extra 30 rwhp im missing! LOL

What is your present lift with the 228R cam running with 1.7 rockers.The 1.8 ratio rockers will increase the valve lift by approximately .032 and dule springs should be used.You also need to take into consideration the ramp speeds of the cam to be used.Quicker ramp speeds will make the valve train less stable at high rpm's with 1.8 rockers...Comp has a grind of cams that are engineered for higher ratio rockers. 
If your cam lobes are not overly aggressive and the 1.8 ratio rockers were used then you could possibly see a increase of approximately 8 HP.
