Hey 1JohnnyO, thanks for giving me Harold's ph number. He is grinding me a hyd roller now with 231 & 239 dur at .050 and a lift of 626 straight across. I would have liked to have gone with a little more duration but since I am running disc brakes front/rear I was concerned that I would not have enough vaccum. I can't wait to get the roller installed & got a killer deal on brand new Comp Cam hyd roller lifters for $250. Thanks again
