Technical Loose rocker

Engine is at the shop that built it, they are going to inspect and clean the passages. I purchased Elgin retro lifters HL-4001S, what cam should I go with? Thanks for all the help guys . This is my first engine I’ve had built. I’m learning so much

 

This is a pretty good assessment. ^^^^ No one will ever see it but it could have had the stud loosen.

 

I'm curious to see what the Oil looked like. Was it silvery?
