They look OK visually, but it would be best to mike them and compare to the original specs. The main inserts may have the size stamped on the back (std. or how much undersize). If the engine has been rebuilt the rod inserts could be undersize on the crankshaft side and oversize on the rod side. Mike the rod journal to see if the crank has been ground and do a little math to see if the insert is oversize on the rod side. If you need the specs let me know.
