Im wondering if the 10 or 7 bolt is better on an xvalve? Reading with interest about the Devilmag, and how they use the level 7 bolt instead of 10 because of faster rof and better efficiency. Whats the reason for that? And how ould i put the lvl 7 on the xvalve?
I also have a SS venturi bolt from 32*. How would that work on an xvalve?
