Paul, I am aware of the 18-degree valve angle, but I seem to remember that they used to have to notch the tops of the bores if they tried to run 2.02" 340 valves on a (smaller bore) 318.

Just thought a 273 might need a dose of the same medicine to enable it to utilize 1.88" intakes, regarless of valve angle....
