Thanks for the info. I'm going switch between 87 and 89 and see if it's happy that way. That last post about a blown head gasket got me worried, but I think it's really just the octane was out of whack.

Resoldering the LKM, as described on the web, did the trick nicely for the headlight issue. Not too complicated.
