Gains from TSP Stage 1 LS6 heads?
So heres the deal. My setup made 404/382 with stock unported 241 heads. It's got a g5x3 cam. The thing is that I DO NOT want to flycut my pistons. I've been told that with the Stage 1 LS6 heads PTV clearance will be fine.
What kind of power gains could I expect to see realistically?

Stage 2.5 have less PtV clearance and therefore would probably need to flycut. I think they add about 5-7rwhp over the Stage 1s.
I don't doubt the Stage 1s make about 40rwhp over the 241s. I'd also buy a FAST 92 to pair with the heads as that will add another 12-15rwhp. That'd put you into the solid 450rwhp range.

And I'll probably end up getting a ported fast 92 and a 92mm throttle body. I've already had my car tuned once, and I want next time to be the last time. haha

So my plan now is..
TSP Stage 1 LS6 heads
FAST 92mm Intake (maybe ported)
Injectors (what size?)
25% underdrive pulley
Swap out my 1 3/4 headers to 1 7/8
And of course a retune
What kinda power can I expect? Is there any other mods I'm missing?

It would be very a light mill, like I said, just enough to true them up. We mill .007" off our 2.5 LS6 heads to clear our Magic Stick cams which are similar to the g5x3.

I like the 42# Bosch. Just curious, why the Underdrive pulley?

I just installed the PRC Stage 1 LS6 with titanium retainers and dbl springs with a 224/230 cam. I went back and forth on either the stg 1 vs 2.5. For my set up, the additional cost for the 2.5 vs hp/tq was minimal. I think you'll be very happy with the Stg. 1. I love the PRC heads.

IMHO, I would leave out the UD pulley and put it towards a FAST 102 ported with your set up. You'll see more of a gain with the intake... I don't like UD pulleys. Cost to HP is not worth it. Plus it may under power your lights and electronics. I know I like having my A/C work 100% when it's 100+ here.
