My T&D paired shaft rockers were shimmed .060" as well. The trend pushrods I had were too long. I calculated the additional sweep across the rocker. it was .011" compared to T&D's exact speck height.
The cam has .799" lift w/o lash. Ran it 8 years and over 750 passes like this. Then had to mill the heads and deck the block. It now has a .075" shim. Over 200 passes. Never had any valve train issues. I will say when the bed plates were mountd on the -1 heads the end studs that supplied were shorter than I liked. They were replaced with longer studs from ARP .
