I know to go with rubber, put a little grease on in place of hy..whatever that stuff was called in the other thread. Any suggestions on a good gasket outside of the usual Felpro?

Thanks!

Genuine Chrysler (probably NLA) or Fel-Pro rubber gasket. No need or benefit to applying grease or oil. As far as I know, nobody else makes a rubber gasket. You can get one made of silicone, but you probably shouldn't; see here.

Thanks! It doesn't need one right now, but when I decide to adjust the valves out, I'll have one ready to go.
