OK, I have sent a PM to the seller to ask him if he had the "actual" sheet for the heads. If not, my curiosity is killing me so maybe I should drop the $80 and have them flowed (told you I was cheap). Knowing actual flow will definitely help the cam grinder's decision correct?

Update:
Seller never responded so I guess I will have them flowed, then send info to cam gurus for opinions.
I still need to source fuel rails and injectors for the LS3 intake (ANY SUGGESTIONS ON SIZE I WILL NEED??)
Thanks,

There are plenty of options: FAST,Holley,BBk,and others for fuel rails. Bosch,FAST, Injector Dynamics,Racetronix for injectors. 50 to 65 lbs/hr depending on HP level.

Thanks...was mostly looking for injector size recommendation. Shooting for 500+rwhp n/a + a 200-300 shot. Just didn't want to buy too small (I hate doing things twice).

I run the deka 60's, plenty good on that hp level. Like lil john said, you have some rails to choose from. As the nos goes, you are planning on a stand alone right ?

I would say no, it would be way to much coin for a fuel system to handle that. My first set of jets was for a 150 shot and injectors almost maxed and fuel rail pressure drops to 20 psi on the hit. Do the stand alone, e-bay or summit and buy a 1 gl fuel cell ( $100 ), fuel pump ( $130 ) and fuel regulator with some an fittings.

Wow, It's been 3.5 months (if anyone cares and I did say it was a slow build). I did get the L92 heads "re-flowed" and they came out slightly better than stock 300@ .500 and 325 @ .600 (it is what it is) and are 71cc chamber. ??How/Who tells me the correct piston to get 11:1 CR??
BTR will more than likely spec the cam after I send him the flow sheet and goals. Spew away with input/critiques
