Rich,
I have had the pleasure
of rebuilding my motor several times in the last two years due to various internal failures. There is no question that you need to clean out the coolers, lines, thermostat and oil tank if you had metal in the motor.
Last year I searched for a local company with ultrasonic cleaners, but never found anyone. I ended up sending my coolers to a company in TX called American Oil Cooler. Here is a link to an article someone wrote about them;

These guys are certified to repair and clean aircraft coolers. They start by analyzing the remaining oil in the cooler for any metal, pressure test, repair if necessary, straighten any bent fins and repaint. Each cooler came back looking brand new with a certification. The cost was $150 per cooler and turnaround time was about two weeks.
