Building a mountain SRX. Thinking of changing the head. Anyone used the MPI head? What other aftermatket heads are available and how well do they work?

are you looking for something with swappable chambers? or just a modification?

So far, only knew about the peak performance head with interchangable domes. If I knew the ideal chamber size for 8-10k ft, I might be interested in the non changable version.

peak and megapower both make 'em, for altitude it IS nice to have interchangable dones, that way if you wanna ride it at home it's still rideable.
