3 V motor question!

[2007ShelbyCobra]

On the 3v motors, is it 1 intake valve and 2 exhaust, or 1 exhaust and two intake? My dad and some friends had this question, and for whatever reason all went blank on it. :confused:

Rather than one 1.76-inch intake and one 1.41-inch exhaustvalve like its '99 PI predecessor, the new Three-Valve head (bottom)features two 33.8mm (1.32-inch) intake valves and a single 37.5mm(1.47-inch) exhaust valve.
