Your crankshaft drive bolt looks to be a pre mod version. (The one on the end of the crankshaft that drives the camshafts, at the very bottom) These have a habit of coming loose and damaging the cam cover. It is reasonable to assume that as yours has not failed so far it will be fine but it would be a shame to damage that nice cover.
Modded versions can be identified by a bi-hex bolt. May be worth considering. Mine came loose and while the bolt didn’t unwind through the cover the car had to be recovered and repaired. S&S do a mod kit.
