Pushrods And Trick Flow Heads
Just another thing to check. I went with Manton Stage 5 - 7/16ths pushrods in my RB, and had to increase the relief on the B3 spec'd custom rocker arms next to the adjusters to gain more clearance for those fat pushrods. You can see the proximity of the big pushrods on the 3rd rocker back in the somewhat blurry photo. My valvetrain has never been so smooth and quiet at all rpms.
