They are all pretty noisy, if you listen to some running motors on youtube you will get an idea of 'normal'. A valve adjustment may reduce the noise but I guess you already did that? You might also want to check the cam lobes & rocker faces for wear and check that the oil supply tube to the valvetrain is clear.

I had the issue too and I couldn't isolate it. Turned out I found a great mechanic , Steve Marx in Costa Mesa, Ca.  In 5 seconds he said- it the chain tensioner for the camshaft. Sure enough he was right. Sounds a world different since its replacement. Could be many things of course but someone that really knows these cars can isolate and resolve very quickly.

Yes all good previous answers, look at the rocker arms for wear, check to make sure that the valve cover hold-down straps are not rubbing against the cam.

Timing chain tensioner?
Oil pump?
List goes on, till more info is added.

Bill, more info is needed.

Good one Dan!

inherited car from uncle who bought it new. warped head. didnt run. had cylinder head repaired and straightened. valve job done. torqued head according to manual. Same with lash adjustment. twice. Seems like it has a lot of valve train noise but I have never heard one of these cars run either. Might be normal idk.   Smokes when started in morning. Shouldnt with new guides and seals

Your timing chain may be worn. It can be replaced without taking the head off, not a big job.
Also the cam may be rubbing up against the valve cover 'posts' (that the cam cover bolts screw into - they are not very robust and can get bent out of shape when the bolts are torqued too tight).

As mentioned be sure to check the valve  cover hold-down straps.
