What lifters would you recomend for a 540 gen 6. cam is a comp cam 260/268 108 lsa 714 lift.Springs as recomended by comp (991-16). I am looking for lifters at a good price that will work well for street/strip use. I intended to use solid roller lifters, but now i hear talk about running hdraulic rollers with comp "420 lobes". My guess is Solid rollers would work best or?
