I like the multi-layer steel head gaskets.  They probably don't make one for
that application but I've found they seal compression very well without
o-ringing (I either use Yamabond-4 or Gasgacinch as a sealer) and tend to
leak much less oil than solid copper.  I still use solid copper for my KZ/Z1
dragbikes (and put up with the oil seepage), but go for MLS anytime it is
availbable for one of my newer projects.
