i now have a peak performance head with 22cc domes for riding here in north dakota, i also have 19cc domes for riding up in cooke city(8-10000 ft), my question is will it make that much of a difference in performance that i should do the switch or just leave it alone, if so how much better is it?? I really dont want to mess with it if i dont have to.

I dont have any experience with the peak head. However I can tell you that bumping up the compression for mountain use, will improve throttle response. Also helps the mid-range power.
8000-10,000' is pretty high, if it was mine I would do the swap. Dont forget to re-clutch, re-jet, and re-gear. You'll enjoy the trip more, when your sled is running right!!

I am not piped, stock pipe and Bender can. Running 19cc inserts from 4000 ft. all the way up. I am running a little richer jet than when I was stock. Some say you don't have too, but.
Stock I was running 140 at 8000-10,000 with the head I am running 141.
Basic advantage to the Peak head is the cooling.
