I read an artical about the 4 valve vs. 5 valve heads. More isn't always
better. It comes down to whether the stroke is long or the motor is
"over square". The Audi motors typically have smaller bores and longer
strokes for good torque making the 4 valve a better choice. I don't
recall the specifics, but that's the gist. A short stroke motor with
wide pistons makes better use of the 5 valve technology. There is more
space around the plug for valves.
