What do you make of this, hot push rods.

Is it just me or does having soft copper shims under the rocker give pause for concern in the future? I can see these perhaps being crushed a bit and spreading if things get hot, or just allowing the rocker shaft to get loose, and oil to get out. Did these torque down normally?

Sounds like your friend is lucky to have you around for some help... THAT had to be a kick in the head....

Edit to add....looks like I am not the only one concerned by this....
