355 super charged iron heads and block what is the best compression ratio w/10psi

I have decided not to go with a 383 but a 355 instead
I have a dart shp block ,61.5cc world heads(iron,ported between a 1205 and 1206),accel professionally ported intake,runners and 58mm t/b,paxton sn2000 s/c
i have a set of mahle pistons -20cc 3.5"stroke 6"rod
I figure about 9to1 is this about right or should i get different pistons?
what would ideal c.r. be?
I also plan on a nitrous fogger kit further down the road.
Any help or suggestions needed.
Any ideas on cams, or difference between doing 350 or 383 as far as power and fuel economy?
how about headgaskets(felpro mls or copper and do coppers last on street)?
what size fuel injectors and other fuel system mods?
should i use fmu even though I will have dfi or fast computer control?
also any good links for this project
any thoughts on pros and cons of dfi or f.a.s.t. fuel injection(haven't decided which to get)?
This is my winter project and would like to get a good thread going on here because I don't have much s/c experience.
Come on Guys I need some of your wisdom
Thanks

15 psi on an LT1 was all 42# Ford racing injectors could handle on the car that I have (motor now dead.)

This is from Procharger. EFI. 9/1 w/o intercooler run 7-12 psi boost BUT that is with ALUM heads. With intercooler 13-18 psi. 92 octane
