"with all kinds of slaps, raps and knocks. But it does run strong"
a bit of a contradiction.

If you are not doing very many miles a yr ('ice cream car') then leave it alone.

Compression test properly done (there are 2 components to a full compression test) will tell you. Also, if the head should ever come off you can look and see and determine if there are burned valves (typically exhaust) by visual inspection.
An easy step right now would be to remove the side cover (you need not remove the manifolds to do this) and check valve lash. If there is little or no lash (I set all my valves to .013 no matter what anyone else says) then you most assuredly have a burned valve somewhere.
Vacuum gauge would also show burned valves and you don't have to take anything apart
The MMO is the best idea since sliced bread!

But my first take is leave it alone!
good luck
