They "look" convincing.
Ya know maybe your right and maybe they are 2 piece and just look 1 piece,"look Convincing" but there are thousands of engines out there running them with no problems and if I were going to give advice on which fasteners to replace on these engines the acorn nuts would be the last I would mention, this is the only point I'm making here.
Replace all the studs, exhaust, carb., mounting studs and these motors work pretty darn good for hundreds if not thousands of applications so far.
