It is the Brit term for what is called in the US porting. that is
modifying the ports and possibility the combustion chamber to assists gas
flowing into and out of the combustion chamber. A good job should try to
maintain gas velocity as high as possible as to low a velocity will cause
fuel coalescence and other problems. At its minimum it is removing sharp
edges and casting flash, it goes from there to "mapping" the port with
the use of a flow bench, static pitot tube measurements and maybe smoke.
