advantage = 16V performance without rocker assemblies, increased fuel economy over true dual cams, quiet.
disadvantage = narrow design hurts n/a performance, no tuneability -------------------- "It's ok to be naked girl... I'm an artist!"

It doesn't hurt NA performance. It hurts high rpm power. NA or FI. The higher angle creates better swirl in the combustion chamber, but it also hinders flow at high rpms. --------------------  |
