Who knows factory cylinder heads ?

You said your engine runs fine? Don't look for something to fix that doesn't need fixing. Saying that your Cam and things are junk is ridiculous.. old and not at its optimum performance very very possible..
I'll give you a picture here of a way to check your base circle. It's for adjusting adjustable rockers and gettingthe cam on the base circle where the rocker should be completely loose. Stamped steel is the term for non adjustable rockers. The rockers are just stamped out of steel..

Thank you my friend. I wasn’t necessarily going to fix anything. But, maintenance is checking conditions. Regardless, I want adjustable rockers. What’s a good affordable set to be added to stock rocker arm ? If they are too expensive, I ll let it go for now. Until perhaps valve train noises increase one day.
