skunk2 pros are definetly great but thats overkill for me (seen dyno's and thats just too much for me to handle). Tryin to build a DD/street with out spending mad cash to make it work (leaving the block stock for a while). Thats why I wanted to try buddy clubs because they work with a stock bottom end and still increase smooth power throughout the rpm. ITR/CTRs are my last option if I can't get this to work, I've ran them 3 times already and they gave me a reasonable gain but looking for just a little more kick. If anything mike, I'll try skunk2 stage 1 or 2 but not PRO series. But the omni valvetrain is definetly what I want since you can get it for less.
