IF they fit under the MP valve covers that is. scope Otherwise it's back to the stamped steel (stock) ones!



I would ditch the springs and put alum spacers between the rockers with a thin steel shim between all spacers/holdowns and the rockers, IMO the rockers will move more smoothly without the side pressure created by the spring tension.

running up my post count some more .
