787 rotary cover score/gouge

[sanchoooo]

Greetings.

I have searched and searched and I can't find anything good on this topic.
I have a 1996 GTX 787. I picked it up used, had one run from it before burning the PTO cylinder. Turns out filter #22 was clogged. I am going to send it off to SES for a rebuild.
I took the rotary cover off, and noticed that it was scored. I have read that the veritcal lines are ok, as they are used for transporting oil, but the circular ones are bad. I just don't know how deep is bad.

I have attached pictures of the cover, valve, and block. I can provide more pictures or micrometer measurements if needed.

Thanks for any assistance.

not the worst i've seen, those are probably ok, since they don't look like they're much deeper than the machining marks.

If the clearance checks out ok I would run that with no worries.
