Sanity check my engine build... anything I'm missing? Trying to get this all planned before I start talking with the assembler who will be doing the shortblock. Tell me if I'm missing anything any of you can think of to get this thing done. 
The goal is to have a really stompy engine, that is still emissions legal for Colorado.
Texas Speed or A.I.R. 383 Assembled Short Block
Trick Flow 215cc Heads
FelPro 1041 Head Gasket
Custom Cam by PG
Yella Terra Rocker Arms
American Racing Headers Longtubes
Ported Fast 92mm Intake
Ported 92mm Throttle Body
94mm Lid
Comp Cams Fuel Rail
Racetronix 42# Fuel Injectors
Walboro 255L/hr Fuel Pump
Custom Pushrods (based on final cam specs)
Cadillac Racing CTS-V Lifters
Stock Water Pump
Ported LS6 Oil Pump
Stock Coil Packs
NGK TR55 Sparkplugs (.38) or NG5 (.5)
Oil Pan.

Obviously, the thinner .041 gasket will give a tighter quench vs a GM MLS at ~.054, which I'm sure you know why a tight quench is beneficial.
I ran an aftermarket set of gaskets (cometic .040s) for nearly 3 years at 11.34-1 and also sprayed the car. I only had stock GM head bolts and even after the #7 ring land went and blew out the entire side of that piston, I still had perfect seal on the head gaskets.
So please, share your reasoning behind this suggestion.

I am assuming the aluminum block, this leaves the energized portion of the fire ring sitting on the thin section of the sleeve instead of the strong section near the sleeves column. If you run a smaller bore cometic or deck the block for the proper piston/head clearance you need you will end up sitting on the stronger portion of the sleeve. You could also look for a piston with the right cd, but that seems less likely as the shelf pistons seem to all run down the bore a bit for a wider fit ability.
