.30 over rings are very common for 22rs since they aresteel rings instead of the stock aluminum ones. As jimbo said a local machine shop can get them if not have them already. There is a machine shop near me which I know had a couple sets in stock. You can also contact japan engines in fremont. They deal with a ton of yota engines.
