Pick a random horsepower number between 330 and 475. That's my guess. 
You can play guessing games all day long, but it honestly won't accomplish much until you nail down true specifics. The heads will be the deciding factor. P/P doesn't mean squat. You could get an 8 year old kid to P/P heads. You could get a NASCAR machinist to P/P heads. There will probably be a difference between the two. Odds are the performance of your heads will fall somewhere in between. See what I mean? It's all just nearly poinless internet guessing.
