Difference between stock VW head and mine
We are using Ray Vallero's daughter Lynda's heads off her racebus from 1983. Because of time constraints in getting this motor done, as that will eliminate some machining (still going to remove 20 cc's off the head and reseat the spring sockets).

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.
