These heads will have 238cc intake runners ( the same runners as the LS6 head), 83cc "D" shaped exhaust runners ( the same as the LS6 head), 72cc combustion chambers, 2.05" stainless intake valves, and 1.60" stainless exhaust valves.**
1.) I was told that with my stock heads since my compression is stock that these heads will drop my compression to about 9.2:1.. Is that correct?
2. I'm concerned about the .650" dual springs, super 7 locks, and vitonrubber seals? Are they as good as the type of components I would buy seperate. Like comp cam 918's.. Don't the 918's come in dual? Aren't they the best? I've also never heard of Viton and Super 7!
3. What about rockers, lifters etc etc. When I buy the heads I'd like to have a complete head with the best bad *** valvetrain that will run with my planned mods.
As most of you guys know I'm planning a turbo kit and plan on using the GT2-3 cam with it. So since she is my daily driver and my hp goal is over 600 I'd like to get her down right the first time.
I don't care if the valvetrain is loud. That kinda stuff doesn't bother me. I'm more concerned about strength, durability, and reliability.

Do you need dual springs? IMO, dual springs are a set backwards for an LSx if you don't really need the extra pressure (noise, heat, wear, and maintenance are all worse). LPE has been clear that they run your planned cam with stock LS6 springs, and it's been completely reliable. Why mess with success? There's no need to spin a twin turbo motor to the moon.
If I were building a TT LS1 with the GT2-3 cam, I'd run the GM CNC heads with the large chambers that SDPC sells. They are perfect for your setup, right down to the port volumes, springs, and valves.
