Difference between stock VW head and mine

Volvo Engine head porting/ matching exhaust
Gasket matching my Exhaust port on the head.
Nothing spectacular and quite boring to watch but quite tricky to do.
The point on this "process" is to align correctly the Exhaust port with the Exhaust manifold to allow gas to flow without turbulence.
it can exit faster and let more fresh air come inside the cylinder.
In the same time the shape of this port is important :
the very light conical shape is a good and reliable design for Exhaust.
the point is to grind very far to have a tight curve and not only grind to match.
