Valve Cover Washers?

Hey all,

I've noticed that my valve cover washers are non-existent on my 81 300SD. I'm about to do a valve adjustment and replace the gasket. How important is it to have wave washers under those nuts? Why won't regular washers work?

I'd much rather buy washers from my local hardware store than spend the extra money and time waiting to get them from mercedes******.com.
