Howdy folks, I am getting the top end together on a 440 and have Isky adjustable shaft rockers. They have solid spacers and shims. I see them on Ebay with springs but I think using the spacers and shims would be better. Looking at the rocker body at the pedestal area do the shaft hold downs keep the rocker body from contacting the cast iron or should a shim go between them? Also if a pic is available it would help. These are the ductile not aluminum rockers. Thanks..
