Either of those rocker arms will perform well if they are set up correctly. Usually they require the rocker shaft to be moved up and toward the intake side of the head. I have the Comp version but have not installed them yet because the roller tip was so far toward the exhaust side with Edelbrock heads.
I suggest you call Mike at B3 Racing Engines. You can purchase the rocker arms through him and purchase a correction kit at the same time. That is my plan as well once funds allow it.
