Lots of stickers (the 5hp ones) and a catch can should do it..
..
Seriously.. interested in the same and know it will be close but maybe not quite.. 480ish is pretty dam close.. If you have ever operated a vehicle with that kind of power the grin will cover the balance of the 20.. Not sure heads are worth the extra but if you really want to get there that could just do it.. Keep us posted. Don't worry too much about a number.. You will be happy unless you go FI and break open the checkbook for real..
