full roller rocker's are not for the street, they are ment for a race car, running WOT all day long. roller tip's are a good idea. they are more uniform in ratieo then stamped, they are stronger too.
the roller on the tip is there for a # of thing's. the main thing is less friction and a more positive uniform opening and closeing of the valve. also the contribute to less valve train where and tear.
for the cost a set of comp cam's magnium roller tip rocker's it is a good deal. on my motor they helped make about 10 more horse's but that is from there 1.52:1 ratieo. the motor also run's cooler and is more resoponsive. the new LS-6 uses roller tip rocker's so that tell's me the general think's that they are a good thing.
diesel motor's have used roller lifter's and roller tip rocker's for year's because of the benifit's. dowm time cost's a trucker money, so the maker's want to limit that! or there product's do not sell.
hope this help's, roller tip rocker's have been around for year's and are a good product and they are worth the money IMHO.
