I use a fine file works good, you can see what material you are removing, use a wire wheel to clean out the ring land.
Good idea to seal that intake when you put it back together or it'll do the same thing over again..
I agree with those who would use that piston with a new set of rings...and also judging from the fact it seems to be more about surrounding a transfer port than being more uniformly across either the exhaust (most usual with heat) or intake (lube issues), that seems to signal debris of some sort hurt that saw or possibly a cold seize. Maybe a bearing cage, or something being sucked in from out side? Was the air filter ripped? Had you already cleaned up that piston? Was there aluminum transfer on the cylinder? If there was no aluminum left on the cylinder, just scratches that also points to debris or cold seize, something that happened quick.
Was the piston cleaned after removal, or did it look like that when you removed it? To me it has marks of a piston stop being used........ Also i would take a good look for the crank bearing while it is without cylinder.
I have a 51 ( non epa ) and it has developed running issues, goes lean after a while on wot, impulse line or fuel line or .......
If it comes to replacing the cylinder and/or piston i will be checking these:

The 55 closed port cylinder is 45mm, and the transfer port design is better than the current aftermarket options.
Something you want to keep if possible...
Got new parts ( intake side ) on the way. Is adding small amount of sealant to the intakeboot wise?I have a Huskie 353 with a Hyway top end and it runs fine. This Hyway piston is 46mm and will not fit the 45mm OEM Mahle cylinder. You may want to check your intake on the 51. They are prone to leak at the intake boot at either the cylinder side or partition side.
