Keith,
I worked with Babe when I was at Sig's in the '70s. Babe was always more "down to earth" than Sig , so when I left Sig's ( at the point he sold it to Super Shops) , I worked with Babe on all the cam ideas I had. Steve began working there and evidently knew me by reputation and we quickly formed a friendship that is still going today. When the loss of zinc caused "the majors" to have failures , Steve and I talked about increasing the lobe taper to overcome the "issue". Done deal no flat lobes. That is why I can say to you it's no big deal to move the lifters around.
