That's a tall deck motor, so about the only thing I can think of is booster to valve cover clearance. But it's not tight in stock form, but with tall covers to clear roller rockers plus the deck height... worth measuring.

Also exhaust has to be totally custom because the heads sit higher.

Was the 596 really not enough? That's available in short block, bolt-in in place of a factory 402 ;-)
