THEY were the verticle bar lifters from comp cams. Their cheaper ones."super roller lifters"
At that time I incorrectly thought that lash would get tighter when hot so I set the lash cold at .028 and .030 per the cam card. This was my first solid roller . My opinion is I probably had way too much lash when hot and beat the lifter to pieces. The link bar was broken and the lifter obviously turned sideways anf ground the cam up. The roller wheel was also in many pieces. don't know what broke first my guess is the roller. This was in 2002.
live and learn.
