My 422 smallblock build

I always like to fit this up before I but my crank in so I can stick a 1/4 inch metal rod in the number 1 main bearing hole. Block the feed hole and you are screwed

That’s what I’m afraid of, blocking the #1 main feed with a pipe plug that is too long. The cup plug that I got is a little shorter than the threaded pipe plug but either would block the main feed a whisker. I’m probably splitting hairs here but I want maximum oil flow. I’ll probably end up milling the pipe plug down a hair and calling it good.
