[QUOTE="GTBill, post: 10302539, member: 67515"] if i was you i'd keep the NPI heads and get those worked. there's more "meat" on them and they can be honed more then a set of PI heads, also they make more compression (mill the shit out of them). make sure to get a quality valve job while you're at it, actually mines well get bigger valves. if you want to save money/time/headaches don't do it in "stages". do it all at once, while everything is out of the car. the 4.6L 2v engine's limiting factor isn't the size of the bore, it's the flow of the heads. if you get a set of nice heads, you shouldn't have to worry about a bore. although, you will need a forged rotating assembly for the kind of power you're talking about, so maybe a .20-30 over kit, i don't know. i'm sure someone more seasoned on here does know, though. don't forget to "beef up" the rest of your drive train. i'd recommend a t-56 with a spec 3 clutch (love mine) and some kind of beefed up rear end (im clueless there).
