My vote is the T&D individual shaft rockers. My Engine guy Tom HEMPHILL ordered the Jesel & got to looking what it would take to make them work & decided to fall back on the tried & true T&D that he has used for years on B1 stuff.
One thing to watch for is when you install the rockers make a few pulls & check to be sure the rollers aren't locked up. Mine were soaked in oil for a day or two like the instructions say & 3 were stiff & it scored the roller. One had to be replaced the others were removed, polished & reinstalled.

GOOD LUCK
