I still say go larger, like the 224/227 that Thunder offers. Anything from them, Texas Speed, or Futral will make good power. Don't get me wrong, I can't say too much bad about the Hotcam being bad, it's just a challenge to get the idle right and eliminate surging. Also, look at getting a kit with 918's so you will easily be able to go bigger later on without buying an all new spring kit. May cost more now, but it'll save you in the long run.
Just my $.02, but I'll be having the Hotcam kit for sale before too long myself, and I'm making 400/405 on it right now, so I guess I can't say too much.
