There is a little more room for individual ports, and for the intake and
exhaust manifolds since they don't have to compete for limited space.
Frequently crossflow heads are used with dual overhead cams, meaning you have 2
rows of valves. The intake valves cant towards the intake manifold for better
breathing, and the exhaust valves cant towards the exhaust manifold for better
exhaust. There are lots of different engine designs throughout history, but
this is the optimum arrangement that everybody tries to achieve.
