Hello the plugs in my 79 ea71heads came loose. what is the name of these or anyone have a part # or advice to fix?

Flatten them a bit to increase their OD. Use some loctite 609 for retaining. Pound them in with a socket.

20 mm brass for EA81 and 82. Three per head. Dunno if ea71 the same? And GDs socket suggestion ...use socket that fits inside the cup and that is where to belt it. But loose fit socket of you might get socket stuck as it shrinks snug tight. I think it is 0.15 mm larger than nominal hole size to stay jammed in over all the expanding contracting going on
