Were the #'s obtained with Cali compliant emission guidelines still in place? If this is the case, that is ****! I live in Florida and we have ZERO emission regulations 
I am building a LQ/415, but might bump to a 425. I will be running Stg 2 WCCH L92 heads, Vic Jr intake (a Cary intake if I have the $$$), 4150 and more than likely a Pat G spec cam.
What I am seeing as the biggest difference between my build and yours are the heads. Even though they are Stg 2 WCCH, they are still L92's; how much of a difference do you think I would see with them vs your LS7 heads. I wish I could run the LS7's, but my foundation is a LQ block. I will also be in the 11:1 range on my CR, but since we have a higher Oct level here, and seeing that you got away with 12:1 CR, I might bump that too.
