Thank you for all the comments, very much appreciated. I will pull the fuel stand and remove/cut the tube and look at the oil pump closer and return with what I find. From what I've read so far, it doesn't sound like these motors used shims although it wouldn't be a bad idea to check because there's always that possibility. It would also be a good opportunity to plastigauge the rear main depending on what I find with the fuel stand, tube and pump.
