5.7 Carb'd Swap on a Reasonable Budget?

Well, I scored a OCP intake (dual plane, carbureted), and I have a 750 Street Demon (TQ style, phenolic center) carb, so ignition (MSD6) and induction are covered. Bought some PAC-upgraded 6.1 heads (smaller chambers/bigger ports & valves), so now I can go up to .600"plus on lift. Just trying to finalize a cam grind so I can finally select the amount of piston dome (compression). I think it's gonna be a drop-in DSS piston/ring set from Summit, just need to examine the bores good. My instincts are warning me to say conservative, with all the good Hemi flow available, so I was thinking a 219/227* .600/.575" 112*LSA cam from Howards. Then a 234/238* .585" 112*LSA shows up cheap, lightly used... Uggh
