If you want a simple, sure fire way to run at "appropriate temp" remove the T-stat and set up a recirculation loop. IIRC that was the original A-4 set up.

Did you ever try removing the bypass valve & check valve, and installing a straight piece of hose from the tee at the side water plate to the bypass inlet on the thermostat cover, as John Cookson suggested? This should produce almost no restriction in the bypass circuit, causing most of the cooling water to bypass the block, and the engine should heat up quite rapidly. If it doesn't, it means you're not bypassing enough water for some reason. Perhaps some pictures of your plumbing and your thermostat mounting will give us some clue as to what's going on here.

Finally, heat!!!!
After exploring every avenue suggested, and some, I took the thermostat and plugged the 1/4" hole and drilled an 1/8" hole in the flange. The motor heated to 180 with the bypass fully open. Closed it about 5 degrees and.......wait for it! The temp dropped to 155-165 and stay there at cruising speed for an hour. I will monitor the temp but this looks like a solution to too much water flow. As long as the little hole doesn't plug, it should be good.
