273 commano on the dyno wooooow

Who needs 2.02 valves? 1.88 360 intake valves would do just fine. Its only 50 thou bigger (on each side) and I dont think it will hurt anything. If you feel it is shrouding, you can notch the bore as the most head gaskets today are 4.08 fire ring bored unless you get dedicated 273 or 318 head gaskets.
