The first pic in this series shows the bowl area complete, but the roof of the port has yet to be touched. The second pic shows the finished roof...this was not excessively ported, maybe 1/16" of material has been removed.
Next is the intake port side at the center divider. There is a slight bump here that coincides with the head bolt hole between the intake ports. Some material can be removed here, but being overzealous with the grinder can break through to the head bolt hole. I started by grinding about 1/16" of material away at the 'peak' of this protrusion, shown in the photo. Once this is done, then the entire side wall is lightly ported....basically the carbide is simply floated over the surface to remove the surface roughness and to blend it into the protrusion that was just ground down.
