Mine has no cross-hatching. It's a light grey color with a really satiny finish; looks like the surface has been lapped. I checked in the shop manual, and it says that's how that FRM stuff is supposed to be. Says no honing is necessary nor is it advised. It says you can lightly sand the interior of the cylinder walls with 600grit aluminum oxide sandpaper for ring seating purposes, but otherwise not to hone them. Based on how well the old rings are still seated, I'd have to go along with that. Boring is highly discouraged because the material apparently has a tendency to flake and chip due to directional stress it wasn't designed to withstand, which is why I'm still up in the air about taking care of that ridge at the top or not. In the end, it's probably not important to take it off.
Still missing parts to my head - It's warmed up a bit since I last posted, but it's still below freezing cold, and I haven't had time to go tear apart my garage looking for them. After further examination, it also looks like that head is going to require new valve guides - there's a bit of play....but I should probably have an automotive machinist check them out - I'm unsure what the tolerance is. I figure for best results, replace them anyway....but I know that isn't cheap to do. We'll have to see.
