I have stock rockes with all of the hardware I'd sell for $25. The ones you're bidding on are the way to go. I got a set of those on Ebay for $150 brand new. Which is the only mod I have done to my motor. They really help with reducing friction and heat in the valvetrain and give you about 40 thousandths more lift and more duration, so it's like adding a small cam without all the work.
