Who knows factory cylinder heads ?

Reread post 2 and 4. If you have stamped steel, non adjustable rocker arms. It is NOT a solid lifter.
Thank you. When you say stamped steel. Do you mean numbers stamped into them ? Or just stamped as in produced ? They are definitely steel and definitely no adjustment bolt or nut on rocker. There were definitely part numbers stamped into them. I was going to take a picture. But, I forgot. I’m not near the car now.
