Thanks for the posting on your thread about the lifters. I looked into the no needle rollers and swapped them on the advice of Crower prior to installing the ones I had so it only cost me the difference.

Now maybe a belt drive to isolate your springs from engine harmonics would be a good idea. I know they are expensive but they have some advantages, one being the isolation piece one being the adjustability and then there is the trueness of timing and ease of maintenance.

The new shoes looks sweet
