what main bearings do you use in a slant 6

What brand main bearings and part # if you have them are you using in a 1966 slant 6 engine. I have been using Michigan brand 1092T for the last 2 engines but I am having questions about these. Just wanted to see what the rest of you guys are using. May need to change. A lot of places dont have them anymors or they are higher than a cats ***. thanks, Bill
