DonE,
Correct me if I'm wrong, but the sounds appears after the engine is up to temp or after short driving period? It is quiet when the engine is cold? You said the sound it makes is like a "card in the spokes" after you have driven it?
If rocker arms and lobes look normal, then it's got to be an exhaust leak....header flange gasket, header weld cracked, turbo flange gasket(s), wastegate flange gasket, cracked ceramic on spark plug, or.......busted head stud? But you did state your compression was good.
I'm also assuming the sound is the same whether the clutch is in or out.
