Timimg might be an issue but to fast flowing of the collant will cause this also......back in the 50's, they use to install washers (flow reducers) in the upper rad hose intake to slow it down giving time for heat transfer.......

Those restrictors are a bit of contraversy in the circles I travel in. I do understand that if your water pumps are those new style ones with the curved turbine blades they recommend that you use restrictors. Otherwise use something like 160 thermostats.
Hope one of those works for you.

Just an fyi- my dad (in his 80's now) is an ol salt flats racer, still has a 3-window (purchased in the early 60's- barn find in West LA), with a 1948 Merc flathead (one of his original race engines from 1949- turned 211 at El Mirage in a streamliner & 149 in the flying mile in a 1936 coupe)....he still runs a restrictor in the upper radiator intake with a 165 degree thermostat....runs typically 180 degrees in all weather....and he still likes to jump on it to show a corvette or two just exactly what a flathead can do (grin). He ran with art Christman, Stecker Brothers, SoCal speed, Speed Donaldson, Jerry Green, Futz, Agajenian, Ed Eskenderian- was well known in the area of Thunder Alley for his engines (one was featured in HRM in 1955)...and swears it is the best way to keep em cool.
