Just wanted to publicly thank Jeff for the used rocker shaft assemblies and push rods I purchased from him. I installed them in my 455 and it is now no longer ticking like an old alarm clock. The 3rd rocker on the passenger side was missing the plastic holder, was half cocked on the lifter and the push rod was rubbing on the head. Not to mention the huge gouges on the bottom of the shaft. It still ran surprisingly well tho. Thanks Jeff. Keep them used parts coming. Keith
