Someone here replied previously with that same thought process...the only forged slugs I know of that would be worth a damn for a 383 would be the Diamond flat tops...nice close to zero deck pistons with healthy reliefs big enough for 2.14/1.81 valves...but you still need small chamber heads...
Downside? They're $600...unless you guys know of some more forgings available elsewhere...seems like there are tons available for 383 strokers and for 400s, and 440s...but nothing nice for a regular old 383
