I will have to go take a pic of the torque spec sheet and post it. This procedure is done when your torquing two different metals together. Its was considered standerd procedure from toyota for a long time. Maybe it has changed since the head gaskets have changed as well. Heck most of the head gaskets made for the 22r these days dont even have the steam ports opened up which is just begging for a blown HG.
is that the same standard procedure toyota used for aluminum piston rings
.30 over rings are very common for 22rs since they are steel 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.
