Yes the 861 is what I've been using lately. Less expensive than the 829 but a much better lifter. I've suggested to Comp marketing a few times that they just stop selling the 829 and replace it with the 861 but they do not listen to me. I don't think the 829 even has oiling to the roller so it is really outdated. The 861 has roller oiling as well as pushrod oiling. If you don't need the pushrod oiling you just block it off with a solid end on the pushrod.
