Gasoline, I could go with the fitech unit if I had to. The plan is to use the torque storm pro charger with around 13# boost. Going with forged crank, H beam rods, forged pistons, 9-1 compression. Haven’t decided on cam yet but leaning towards comp cams 550 lift. The pro charger is already set up for water methanol injection. Not sure if any one makes a after market aluminum head or not. So will probably will just have stock head worked over.
1) It's a HUEEEGE jump from 500 to 600hp, those aren't numbers You can just throw around for almost any engine let alone a Slanty.
2) It ain't never gonna happen on 13#'s of boost, I can guarantee You that, unless You're spraying it with 200hp worth of N2O. 21#'s is probably a good start.....BUT......
You might want to look up the gold Duster that is running a charged Slanty in the 10's, that ought to give You a reference to work with.
3) Oh Lord, did You say "aftermarket al-u-minimum head for a Slant Six"?? No, and the better ported heads usually top out at 210-220cfm, I've only managed 192 so far,
but I knew more was there. Mike Jeffries is purportedly one of if not the best at it, and has many fans on Slantsix.org, but I think He's retiring so..........
4) Personally, I would never attempt what You are without port EFI, but that's just My 2cts.
5) I wish You luck, feel free to ask anything, and share the same!
