Another Overheating Question

[mgm60]

I know about a million words have been written on this subject but here's the questions anyway. This past weekend I replaced my upper radiator hoses because the old ones were mismatched. I included a picture of the new ones which are the same 1.75" I.D. as the old ones. First drive afterward the Temp gauge topped out after about 10-15 minutes. Had a small amount of overflow from the radiator, but could hear coolant bubbling in the engine. Tested the gauge, which is the old liquid type, and at 180 degrees in hot water it shows 3/4 to top line Normal and at 190 right at top line. This is the range the car ran at before the hose swap. Also tested with an Infrared Thermometer after a test run (temp gauge topped out again) and read 190 at the upper outlet and inlet and 210 at the water pump and top of the block. Not running any thermostats and setup with a Mallory Electronic Distributor.

Any thoughts on what to check next?
