Hi
This could very well be the problem.
I once had a customer with the same problem with a Harley Davidson. He had put a lumpy cam in and changed the valve springs and retainers. The high lift combined with the new bigger retainers was causing the underside of the top retainer to just kiss on the valve guide and bending pushrods. (he was using solid lifters) another problem was that the top retainer was hard against the rocker cover which was also causing some spring bind. A quick touch up on the linisher fixed the retainer but had to remove the valve guides and knock a little off the top of them.
