I'm just going off the case and valve cover. Looks flat black. Actually, I was told Honda used 60% gloss black.

Good score, I love it when a seller gets in over their head.....:-)  The rebuilt head is worth twice what you paid if you have priced tools or shop rates lately.

Yup money well spent. Definitely an F motor. If the valve guides were not changed you might want to replace them if you plan on running that motor. Something to consider anyway. The F's are known for guide wear. Also, don't lose those 2 little oil jets on top of the head. The only thing keeping them from falling out is the o-rings.

Oil jets still there  ;) definitely looking inside to see if the guides were replaced.  Not in a hurry though. It needs to be stripped and painted.  This will probably go in next fall. That's my hope anyway.
Pistons marked 410... rings look new, but I'm not sure.
Too many unmarked baggies, cups full of bolts, screws, widgets.
Sorting and comparing to my HM book and fiche will suck, but i will learn.
