Those APE nuts look like black oxide which is crappy in terms of rust prevention. The metal is likely (much) stronger than stainless though. Take your pick...

Nessism your are right about APE nuts but without any (much) stronger APE/PMC [studs it´s a waste of Money!
For normal use SS nuts are the better choise....

The APE nuts are a race part. Made super strong to be used over and over. Much stronger that Stainless steel. The finish is black oxide for appearance. It is not a rust preventive.

Give your head nuts a bath in phosphoric acid and they will have a zink plated layer for rust protection.

If you follow the torque patten, yes
Temporary use the old head nuts to hold the headgasket under pressure.
