stock 243s increase?
#6
Might have been me. I picked up 27rwhp/10rwtq. That's through a 12 bolt w/4.11s and a M6, but it had the same drivetrain before the swap (same tune and everything else too). The real nice part the dyno doesn't show is the ~4mph increase I saw in the quarter. My results are not typical, lol. I have another set I have been meaning to send off to Advanced Induction for their killer port work but I have to say the stock LS6 heads work great. Still have me grinning even after 3 years. In fact I am putting an almost identical motor into my 96 WS6, but with a LS6 intake (instead of FAST) for boost.
Very long story short, 15rw sounds right for an auto.

If you are going to put the effort into changing the heads, retune, etc., you might consider milling as well to bump your compression up further. That is free power since you shouldn't have PTV concerns with that cam.

If you are going to port your heads go with Advanced Induction. great people who know what they are doing. in this dyno section a guy sent them out to AI and after those heads boosted him 49rwhp/32rwtq!
