38M190455 decodes to
3 - Olds
8 - 1968
M - Lansing
190455 - 190455th car down the line

The valve covers are GM Performance Parts units and retail for $300 a set new last time I checked.

Beyond that you'll have to open it up to see what you have. That looks like the big car (88/98) air cleaner, so assuming it started life on this motor I'd expect small valves, unless someone has upgraded them.

Are those motors worth anything? I have an Olds 455 in parts car right now.

Yes. Post it over at realoldspower.com when you're ready to dispose of it. Don't mention you're a Chevy guy.
