Engine masters did a whole dyno test on all types of rockers and there was almost no gain from a full roller rocker.

The actual rwhp difference will be around 1-5 rwhp on the dyno nothing you will ever notice and it will not change your ET it will be very similar or the same. The TFS225,AFR260,and TSP260 are all excellent choices you can’t go wrong with any of them. I would lean towards the AFR260 though depending on what camshaft you use I really liked the torque curve with the AFR260’s.

thanks Blueovalman. I just realized that the thread title could be misinterpreted.

i may have come up on a deal on a brand new set of part# YT6733 from a friend of mine that went win small LS7 heads from WCCH on his car and needs to get rid of some of the LS3 top end stuff he had being piecing together. he wants $500 and im thinking im sold on them.
