What I meant to say is, I run the Jessels and they are pushrod fed oiling individual shaft rockers. They work great, but required alot of machine work to fit. I also run the single shaft T&D's and they worked fine, once the pushrod length was perfect, and I mean it needs to be perfect. But when I build my next rocker system, it will be with T&D individual shaft system, because they don't require the extra machine work that the Jessel's do. I have also used the Koffel black rockers, and they worked fine for me. I did order the torington bearing kit from Tom Hemphil for the rocker shafts. He is in PA and can help with that. But if you are set on individual shaft system, pushrod oiling is the only way to go IMO.
