Youll need porting and big cams to get 220hp. Its not as simple as you might hope. Camming a 20v is a bit pricey.

Look for cams from hks or trd, toda. Generally the easiest place to get them would be off the forum sponsors here, or direct from Japan via Greenline or Nengun internet sites, lots of other hot up bits available too from those sites.
I dont know much about pass racing but it looks like ebay crap to me. Look for reputable japanese valve springs.
