Filing rings?

[Chris727 1,705]

I was watching one of those performance automotive shows and they suggested to file the sharp edge off the outer corners of the rings in order to avoid scracthing the cylinder during installation. I was thinking of doing this on my K341 rebuild. Is this a good idea?

I use a ring filer and then meticulously de-burr with hand file - always.

I guess if you were building a supercharged 10,000 RPM racing motor with a 13:1 compression ratio, that would be a prudent "blueprinting" good thing to do. Tom (PK)
