Question for the brains trust
I'm giving my cylinder head a clean up and port match and came across the below.
The inlet port seems to neck down as soon as it enters the head. Basically a little lump that blends through the first 4 or 5cm of the port. Should I remove it? Inlet manifold runner is straight and parallel. Is it to increase velocity where the fuel is injected? Is it just a restriction.
Engine is a Hyundai beta2 g4gc. Will be getting big cams and 11/1 compression.
