I pulled the engine to replace the motor mounts and swap the oil pan with a cast iron one since the oil plug had a reducing bushing in it to fix worn out threads. First worrying sign the pan had a film of silvery powder in the pan. I then noticed what looked like blowout of the head gasket so I decided to order some head gaskets and got around to cracking the head open. The bolts seemed a little too loose, so hopefully that was the reason for the small blowout. But on cleaning out all the soot and buildup I found a worrying amount of cylinder scoring. I don't have much experience with small engines so I need advice.
How bad is this? It's didn't run smoky at all since I cleaned and adjusted the carb so it was running well (as smooth as I could expect with bad motor mounts). Is it alright to put back together and use for the winters plowing without doing more damage to it?
Does it need a complete rebuild in the spring or do I just watch how it runs?

To fully answer your question:
All have given you good advice which I agree with first and foremost.
Yes you can run it as it is, if it was not knocking or smoking badly which you say it was not..
Also, winter snow plowing with a blade is usually not at full governed rpm's and during cooler weather which is helpful.
I've seen worse, panting and pissing oil out the breather and fouling
the plug.
Also, your other repairs hopefully will turn out to be successful, but in the event something is not right, it will be addressed when you have time to do the re repair when the engine is out for your overhaul.
If you button it up the way it is, do be advised to retorque the cylinder head after a couple of heat cycles. which is not mentioned in the service manual.
You can do a search on here, as it has been covered multiple times.
If this 2nd retorquing is not preformed, it will blow the head gasket again, just a matter of time, and you experienced that as you said the head bolts were not as tight as they should be.
