Heads Cam Suggestion for my setup well... it's getting close to the time where the TA goes away... so I need to figure out what I'm doing this winter.
Here's the plan:
Headers - undecided
ARE Oil Pump
LS6 Intake
SLP Double Timing Chain
Heads -- RGR Stage 2 2.02/1.57 valves ??? do I even need stage 2 with stock LS6 intake? Should I go GTP? or ARE?
Cam -- .563/.563 224/224/112 Comp Cams ??? sound good? Should I go more duration? More lift?
Comp cam springs -- 941s
Chromoly Push Rods
New Lifters and Rocker Arms (stock ratio... 1.6?) (I'm replacing the entire valve train other than the valves)
I want around 400 rwhp. Also I don't care about making power past 6500RPM as I don't want to rev past that point (I know some people spin there motors up to 7000 but I'd rather not spin it that high).
So for those with Heads/Cam and making ~400Rwhp on an LS1 (stock bottom end) what package did you get?
Anyone have any suggestions on a good package to try?
LS6 ported heads or LS1 ported heads?
I'm looking at a max of about 5000-6000 for all that's listed above if it helps (prefer to do labor/install myself)
One other thing to keep in mind, I want to make good power NA, but I also want to be able to spray the car with say a 75 dry shot. (but not until I do some fuel system upgrades)
Thanks for any suggestions
One thing to note , emissions aren't an issue.

Re: Heads Cam Suggestion for my setup MTI Stage 2 or GTP stage 2 heads and something like MTI's X1 cam should put you around 430 to 440 rwhp thats with LS1 edit tunning Hooker long tubes are good but cheap maybe a true duel setup if im leaving anything out please jump in.

Re: Heads Cam Suggestion for my setup If you're not planning to spin the engine past 6500 RPMs, there's no need for a tremendous amount of duration. With stock displacement, you won't benefit that much from the bigger valves, either. If you're going to spray, most guys prefer a 114 LSA, but w/ a mild dry shot, it shouldn't make that much difference.
IMHO, what you need to do is select a matched heads/cam package that is suitable w/ your other mods. If you have access to a "desktop dyno" s/w package, you can simulate various combos before you buy.
