I was a victim of the old Intense 1.9's that were wearing on the sides. I ended up getting the 1.8 Comp Cams Pro Magnum roller tip rockers and really didn't notice any difference between the 1.8 and 1.9. What's nice with the Comps is that even though they are steel, they are actually lighter at the roller tip because there is less mass at the tip than the aluminum rockers. I run the LS6 springs with them.
