That is some collection of stuff right there!!
Is that four boxes of tipped radius lifters? I see the slots in the front three packs?
Question for Pete here,
those lifters the "tipped" one's, you've stated in earlier posts that welding on the lifters is a big no no. And that the needed length should be added to the valve stem. I've seen in old books and magazines pics of these lifters, with that added on pad on the top. Were these pads welded on? Or some other process? Did these lifters have issues?
Look forward to you thoughts on this.
Thanks,
Martin.
Sorry for hijack, but I feel relevant.

The buttons were silver soldered on. They were put on as a convience for back yard engine builders so they wouldn't have to do either that or weld the valve stems at home.
Overall they worked good. I did see a few that showed sagging on the top due to loss of heat treat during soldering process..
I wouldn't be afraid to run lifters with buttons. We have much better springs now.
