Hey guys, which CNC ported heads are you all talking about? I've seen several different kinds. I know TSP sells them, they are PRC. And I see Jegs offers them to. Here is the link:

I also saw others from TEA and Lingenfelter. So which ones do you all have, recommend, and which are you all talking about?
