to run an s1x I need to run 130# and a double roller..?

how many people without this combination are having trouble?

I've been leaning toward the S1X cam and Intense recommends only 105# springs. I don't believe everything vendors say so I am wondering why you recommend more than Intense does on their cam?

Quote from Intense: "The Stage 1X Cam is the IDEAL aftermarket cam for use with stock heads, lifters, rocker arms, retainers, and pushrods. Aftermarket lifters, pushrods, and retainers are not necessary at this level, but there are certain reliability and performance gains to be had by replacing these items during your cam change. We always recommend and/or install CompCams 105# valvesprings with this camshaft."
