We have done several sets in the last few years. They make great power. I've revised the porting a few times now, tweaking and refining.
Guys who hand port Wenzler SC heads must cringe at all the material to be hogged out.
I first started using a Superflow flow bench 20 years ago and it was fun hand porting and testing and porting and testing and porting and testing....
But hand porting raw castings is a lot of work by hand. To tell you the truth, I wouldn't do it any more, I'd rather chew broken glass now. I wouldn't hand port set after set of a raw casting, maybe I'm just getting old?
Since we got the 5 axis CNC it makes it tolerable now because you know all you have to do is develop one port, one really good port, one time and then digitize it. Its nice knowing that you don't have a ball and chain around your ankle and there's light at the end of the tunnel.
