I'm not using the dutweiller cam setup, but do have roller cam bearings. First go round on the mototr the cam sensor ate itself against the cam gear within 100 miles of driving. bad enough to drop oil pressure where the cam gear was not catching on all teeth. Upon tear down the front of the motor was covered in metal shavings, cam gear was razor sharp, and front was completely dry. Seems like since the roller cam bearing block the oil to the cam bearings there was no "splash" out of the front cam bearing to lubricate the timing chain? Solution was to drill tiny oil feed holes in the front galley plugs to spray the timing chain. On other motors the oil pump bypass was plumbed to drain at the fuel pump plate which provided splash oiling. Have not had a problem since.
