 From my limited experience and reading the usual suspects, this is 
only partially correct in that the word "porting" often is used to 
mean more than reworking the intake and exhaust ports of a head. 
Porting often is used when one is speaking of also reworking the 
head's combustion chamber, including and especially the area around 
the valves. Those changes don't require matching to the manifolds.
