Hi, anybody have a pic of what the planing marks look like on a 899 head?
I have a line on a head but don't want one that is useless.

As in the "it's safe to machine to this point, but no further"?
Generally they'll be blank depressions in the head casting on the head to gasket face. If they're there, you're OK. If not, you're not.

Ok thanks, i'm gonna go see the head on friday.
would it be worthwile to have the head skimmed more than necessary for a slight performance increase, or would that induce more/earlier gasket failures?

Worth a little. Shouldn't really hzave any effect on the likelyhood of gasket failures.
