No I did not order risers. When I got it torn down both risers looked really good. the port side manifold and elbow looked really good also. However the starboard side manifold and elbow not so good. At this point I believe somewhere along the way they port side had been replaced. While I had all the manifolds stripped off the engine I pulled all the all the hoses and flushed the block as well as I could using a hose. Also inspected the steering and engine oil coolers. This is where I think I found the real problem. About 2/3 rds of the tubes in the engine oil cooler where blocked with large sand particals. I managed to clean the cooler out carfully with a straight stiff wire. Reassembled with both new manifolds and elbow and ran with a set of muffs in the driveway at about 1200 rpm for almost an hour. The temp on the gauge stayed steady at about 165. I used my ir on the thermostat housing which read about 10 deg cooler than the gauge. Also checked both manifolds in several spots the temps ranged from 95 - 103 deg. Both elbows ran at about 98 deg. I then idled the engine and rechecked temps. They all seemed to raise by about 5 degs. That seemed a little odd to me. Anyway I believe my overheating problem is fixed. Headed to the lake Friday afer work for the weekend. Taking me ir and putting it to the real test.
