Hey everyone I am looking for ideas. I not really comfortable with the engine temperatures on warm days. I find it climbs on the gauge from the 3/4 mark to the 7/8 mark at idle in traffic or when I get on the throttle for a bit of fun. The car has a fresh 272 with 1000 miles on it and has a Ford-o-matic for a transmission and a 2 row radiator that was freshly rebuilt though the top rad tank was not soldered well so I had to fix it.

This is what I have tried so far.
 1. Fixed rad leak in top tank seam pressured to 18 lbs held pressure for 4 hours perfectly and the rad cap tested fine at 13 lbs.
 2. Put on a flex-a-lite fan to replace the stock fan.
 3. Put on a fan shroud it is not perfect as far as opening, but the fan is 1" from the rad and only half way into the shroud it will pull a paper towel into the rad in the front from 6" easily at idle.
 4. Increased the jet size by one number past stock to make up for today's fuels and I only run premium that has zero ethanol.
 5. Set the timing to 10 degrees BTDC.
 6. At idle the engine has a steady vacuum of 18 hg.
 7. Set the valves to 21 thou cold and you can hear them at cold idle then they quiet up as the engine warms.
 8. Engine idles at 500 rpm and has a very slight miss every so often, but seems fine.
 9. The engine has dual 2 1/4" exhaust with no warm up riser on the one side. 

Now any ideas the water pump was a rebuilt from Napa the rad has coolant 1/2" from top edge of rad cap the tank is slanted to the front and when it shuts down a couple tbsp of coolant vents. I am running a 60-40 mix of coolant and water. The thermostat is 190 degrees.  Am I worrying too much?
