H/C/I/E to FI

H/C/I/E to FI
So I've been thinking about going to a FI setup for years, yet never really decided to spend the money. I've had my WS6 for several years and slowly have built up the motor to what it is today. Here's what I've currently got in the car:
224/230 XER Comp Cam on 112LSA
Patriot Stg II heads (bought from my cousin several years ago. Supposedly they were milled .030 to give ~11:1 CR)
Jet Hot LT headers. !Cats 3" True duals w/ X-pipe running through 2 bullets
FAST 92 with NW 90mm TB
stock MAF
Aftermarket lid
!EGR
!AIR
I'm in the process of tuning the car since I just got the FAST on. The last time I went to the track was probably 5 years ago and ran a 12.3 @ 118.9 on a crap tune (with a LS1 intake!!!). That was before the true duals and FAST 92/90. In essence, I have no idea how much power the car is currently making at present.
My desire is to get to 550-575rwhp, and without going to a bigger motor or N20, I am confident I'm not going to get there unless I go FI. I thought it would stop now, but its only getting worse FYI I had a turbo car way back in high school and I loved it. I'm ready to experience the fun of FI on a V8. The bottom end is still stock, so I want to keep lower boost until I'm ready to upgrade the bottom.
I will be going with a supercharger. I'm leaning towards a D1SC. I would like to go SC for ease of install, tuning, etc. In doing some research, I've seen people discuss running boost on applications that have similar compression ratio than what I'm currently running.My plan is to go to a 317 head for lower CR. Selling my other heads for these will net me some extra cash. I'd like to keep this on pump gas.
Now for the questions:
1. Should I sell the FAST for an LS6? Will I be able to get close to my goals with the LS6? Reason I consider this is because, if I don't need it, why not sell it and use the extra money?
2. I know the LSA112 is not considered ideal, but how much could I expect to gain on a blower cam over this cam? Is there a better cam that will allow me to keep the wonderful sound I experience every time I fire up this car AND be more blower friendly?
3. After reading about some of these higher compression setups I'm not sure if I would need to change the heads or not. I can do the work myself, so its not an issue, but I want to be careful with the motor.
To sum this novel up, this car is not DD. This is just the next step. I also want to be sure slapping on a SC doesn't put me over the power threshold for the stock bottom, until I'm able to add forged internals.
Thanks in advance for the help/guidance/flaming, etc.

I'm running rear mount T76 bb Turbo with stock everything except LS9 cam on my 2002 Z28. Came with LS6 intake. Just did 551 rwhp @ 10 psi boost.

Wrap all exhaust and spend a few bucks more for the ball bearing turbo. It's worth it.

Tell him "Hayden referred him, the blue convertible he just built".
He can help you with any technical questions too even if you don't use him for the build. Great guy.

@ HrHohio
yeah I have a forged rod/piston ls6 w/317 heads, was thinking of the Tu1 cam, ls6 intake..
what compression are you on^^
since Im forged would you still recoment the same compression figures??
oh and CMS in murietta is only about 45 min from me so Ill be going there
