Spare parts ?
 

I had a 24 stud 59A block decked and found these in the box of parts when I picked it up. Do these belong in the block or are they spare parts?? I have low oil pressure which according to other post may likely be a missing plug behind the the cam gear. I am checking on that but wondered what these might be. Don’t remember seeing these before in a flathead. They may be somebody’s missing parts lol

Missing bush for fuel pump push rod will cause low oil pressure.

Those look like valve stem wear/lash caps. Most likely from some other engine at the shop.

It started off with 15-20 psi with a known gauge at the port on back of motor and drops to about 5 to 8 psi in about a minute or two.

crankshaft plugs ?

Crankshaft plugs? He didn’t have the crankshaft, I built a Stroker motor with a new shaft, I bored the block, I just needed to have the block decked. That is still a good question to check the new shaft for though.
