1st.thing............relax,take a chill pill! Figure a way to run the engine Before you put it in,,that way you dont have to pull it again.You only need to run a idle for about 5-10 min,and letting it get warm is a good thing.Somehow I missed the pictures of the main bearings.As far as I can remember,journal taper was a max of .001,and if all they did was polish it,they might not have given it more than a basic measurment at the center of the journals.I've had engines that primed much the same way as yours,and some that would make a horrible mess due to the oil from the valve train,even with oil restrictors in the oil galley.I would like to see those pictures,,tho.
