Dave Ett had a head that had seemed some det.

Was going to spin that into a limerick but I can see a FAIL! happening.

Even a real cheap ba$tard as myself would probably not run that head. If you do go for the conversion, you don't need the HRC hose. Just get radiator hosing and loop it from the head to the thermomstat. I think I used a ~24" piece on my MC28 for about 5 years without issue.
