So need some help with building my h/c V... Things I have settled on.
2005 LS6
Fast either 92 or 102 depends on where I find a deal first.
TEA stage 2 heads .650 lift
ls7 lifters
Ported ls6 oil pump
P&P LS2 TB
Comp cams #1500 rockers
Things Im in debate about
Cam? It will be a daily driver, but I would still like and aggressive cam.
Injectors? Can you over injector a car? or can I put on 60lbs injectors and plan for future HP?
Heads CC? I would like to up the compression 10.5 or maybe 11. Are there any draw back to running that on a stock bottom end? Which I plan on forging later on for a vortech btw.
Along with the chamber cc size what head gasket?
Timing chain?
Push rods?
I do plan on running all arp hardware.
Any other suggestion? Trying to keep it on a tight budget because along with all that an 8.8 is oing in so dropping some serious coin at once here!
Im sure that im missing something....Just trying to think this all out before I go shopping happy!

from experience, i've had the TSP MS3 cam, the driveability was there, and it was aggressive. I think with that setup, and a good tune, you'd make 45x RWHP.
I used a stock LS6 head gasket, stock combustion chamber size, the pushrods will depend on your cam (with the MS3, I believe it was 7.425, but do research or call TSP)
If you get a double roller timing set, you'll need to grind out your timing cover for it to fit.
I bought new, stock, for my stroker build.
You'll also need header gaskets, thread sealer for your intake bolts, intake manifold gaskets (assuming your intake doesn't come with them), valve cover gaskets, timing cover gasket, crank pulley puller, coolant, oil, and while the heads are off, the motor mount bolts are damn easy to get to.

As for the motor mount bolts They are new, I put in some UMI mounts when I did my headers. OBX 1 7/8 catless

Stock 243 casting heads flow pretty well and don't need to be upgraded until you've optimized everything else in the system. Having TEA do a stage 2 porting of your stock heads makes sense if you have a cam, but if you don't have one, I think you're wasting your money. As far as the timing chain assembly goes, I recommend a C5R chain and Cloyes Hex-a-Just to take chain slap out of the equation. Wouldn't bother with double rollers. If you don't plan on going beyond a cam, you light be able to squeak by with just a stock LS2 chain, which is stronger than the stock LS6 chain. I still have the stock chain on my cammed LS2, but I will be upgrading to the C5R for my 416 CID LS3/TVS2300 build. Melling High Volume oil pump all the way. Stock rockers are very strong--just buy the Comp Cams trunnion upgrade kit.

with the fast 102, you'll also need an adapter harness to convert the ls2 throttle body you'll also need

Radeon is saying..
If you want to use the 102mm intake, you need to change to the 4 bolt throttle, LS2 throttle is sufficient, and in doing so, you need to either re-wire yourself, or buy the harness for the motor to work properly. (LS6 years throttle was wired differently than the newer 06-07.)
Here are the pins if you decide to do it yourself.
I usually buy from Caspers Electronics Directly

You are. The heads you got are fine. I think he's misunderstanding the original post. Maybe took it as you're not sure if you're doing a cam swap, rather than which cam to swap to.
Also, I used 60# injectors. You'll be fine. Just has to be tuned for them, whether 1lb or 100lb.

FWIW, don't know if this is the case with all V's, but just wanted to mention that the LS6 in mine had the LS2 chain in it, stock.
You should still replace it with a new one though.

Go with the Fast 90 or 92, get with EPS about their 230/238 cam and their rec. valvesprings, ls2 timing chain is all you need, keep your stock rockers their is no need to swap unless you go to trick flow heads.
Much bigger injectors then you need can lead to idle tuning issues. Id go with 36lbers and sell when its time to upgrade youc an usually get 80% of your money back on them.
Also for an n/a setup id say mill the heads to bump the compression which will help a decent amount, but with your plans to go FI it wont be ideal with over 10.5 compression.
