I was not getting a good pattern on the valve stem with the stock rockers. I know I am not going to gain a lot in hp but I want to have some good valve geometry and I am not getting that with stock rockers. I am going to use roller tip stamped rockers so they aren't that expensive. I have been told with my set up and the mods I have made and a 4 bbl carb I should be at 270 hp or a little more. Stock the 4 bbl versions could make 270. Roller tips with the correct geometry could add 10 to 30 hp. That comes from getting the valve opening at max height with the right size pushrods and correct lash.
