I am building an Acura motor (first build ever) I am plastiguaging everything and found that a couple of the rod bearings are a little tighter then the others. Will they wear in during the break in? The engine does turn when you turn it with both hands, not with just one hand though, spark plugs out. Also you can hear some scraping but that is coming from the cylinders, I assume it is the new rings against the freshly honed cylinder. learning curve.

The clearance measured with the Plastigage should be within tolerance. If not, you need different bearings. They are not intended to wear-in.
