My were exactly the same way. The clutch side was very heavily
cratered but it's thickness measured as new. Really confused
me since my endfloat was towards the high end of the spec.
I ended up putting +.005" thrust washers in for an added margin
of safety.

Dontcha' HATE this?! You go to all the trouble of ordering
the right stuff so you can do a proper job on a very
*critical* area... <$$$>
I dunno...perhaps others can jump in here and tell you that
they've used zinc plated main bolts with no problems. Otherwise
you might want to call the vendor and ask him about it.
I can't think of anything wrong with zinc plating, per se, but
I've never seen it used here before. It has me wondering about
the the past threads on conterfeit fasteners.
Best regards...Tom O'Malley
'74 Spit...no steenking plating!
