measuring cam lobes/intake ports

[koabi at seeohdee.com (koabi)]

I may be looking at an engine that supposedly has cams and is ported and
polished.  9A 16v (9A head too)

I will be buying a micrometer.  Where do I measure the camlobes and if
the cams are stock what measurement should I expect?

I imagine measuring the intake port will be harder, as the head could be
ported without making the measurable hole that the face of the head
bigger.  For fun though, what would be a stock measurement for that?

TIA,

Up to no good.
