Small block bearing clearances

Actually this time the bearings dont show any signs of heat.last time at the tighter clearances they were looking kinda rough.The bearings right now are a hard,coated race bearing.Also narrow.Last ones were wider and champfered.These are just narrow.So am i hearing leave them as they are,that being the larger clearances,and just run a better oil?The coating is starting to wear very sightly,and under that it looks chrome.I would rather not have to replace a 300 dollar set of rods and mains if they live as is.It sees very little street duty
