So I have rebuilt the engine on my Puch Newport. The other day I was just cleaning up some of the loose wires and making sure everything had kinda "settled into place." I found though that one of my cylinder stud screws on the bottom right doesn't seem to either hold tightness or it never fully tightens. I am just wondering if I should replace the cylinder head studs and nuts, but I have also heard that nothing I will be able to get will be able to match the quality and strength of the original studs. Any thoughts, I am just worried that it could potentially mess something up in the long run.
