they use a paste to define the ports , as so to port match both sides of a flowing area. IE head inlet to inlet manifold , or exhaust manfold to head outlet etc. Then , one side is ported to properly match up to the other
Extrusion paste smooths out every burr etc

is that worth it. or would i rather just get it hand ported? or cnc ported?
