im thinking of buying these. all of u guys with em, please post up. what kind of numbers did you gain, do you like em, and did u keep ur stock springs? also did you guys have it tuned? i know that i should have it tuned and change springs, but i plan on doing heads next year.

 

you can go mhs stage 2 without changing valve springs...just thought id throw that out there

 

Both kugzgt and i have MHS stage 2's which are almost identical to CMS stage 1's. Both have stock springs, and everything is fine. I spin mine till 6200-6300 rpm with no float at all. You'll be fine.

Don't pat too much attention to dyno numbers (read my thread on my install/results write up) as they can be very misleading.

BTW kugzgt, how high do you spin yours to just out of curiosity?
