I was looking around on ebay and i came across a performance head made by Mountain Performance. it has 22cc domes so you could use them from 0ft up to 2000ft. If i were to buy this what kinda of results would i see from this, how much of a power increase would i see. by the way it will be going on my venom (same h.p. as the sxr 600). would it be a good purchase?????

no real power gain. they just allow for the head to cool better and you can change out the domes to suit your needs easier (say going from sea level riding to elevation riding) and such. they are not a bolt on hp mod.
