tbi 350 to sfi?

i have a 350 out of a 91 Chevy. i need to know what all i need to do to switch it from tbi to sfi or another type of fuel injection. i don't care how much work it will be i also need to know what anyone would recommend for new heads, rockers, pistons, cam, and intake and anything else i have left out. i would like to get around 375 horse power or so. any help would be greatly appreciated.

You said you did not care how much work it takes, but you did not say anything about money. Have you looked at the Holley Avenger MPFI setup? You can get a complete multi-port injection system, but it starts at $3000 and goes up as you figure all the other parts you need to buy.

For EFI maybe you can either modify the TBI setup (if you have all the parts already, I know there's people that make good power with TBI) or use a TPI setup, possibly with a modified LT1 intake?

i have looked at a couple multi port systems but im not really sure what to go with. i want to go fuel injected im not big on carbs and i have looked at aftermarket tbi but i was told it would be better to go with a newer fuel injection system more more fuel milage and most of them support up to 400 horse.
