What I am saying is this thread is a good read. When Banning lived in Bewley, Ontario we would go there a lot. He would put those tubes in the Stage V Heads but were much bigger for a larger push rod.

So the problem seems to be on the Exhaust side of the push rod tube. Lowering the ratio seems to fix the problem with some rockers. I wanted to go the Stage V rockers way and might have to give Banning a call and see what he thinks and if Stage V has a 1.5 exhaust Rocker or something atleast under the 1.6. The final thing will be to mock up the motor and take alook at what clearance is there. The only problem with T&D is the price but you only want to do it once and not have to do it twice if something happens. If you go with a stock Factory type rocker then who would sell the most accurate ratio or is it just buy and hope things add up after checking. Quality control at it best.
