Air leaking past piston rings?

It is a stock bottom end. I did replace the piston rings but had to trim them down because they sent me rings for a bored 318. Just needed some reassuring about it leaking out. Thanks guys

What size rings? When file fitting rings, typically a .005 over ring is used. Might not be a good idea to file fit a .020 or .030 over ring.
