Champion "iron" head question?

[robertf]

Always wondered, I'll keep it simple. Are all Champion irons ported/CNC ported?

Yes, they are ported stock heads.

Anything that was purchased in about the last 15 years starts off with a CNC contour and squaring. The important areas like the short side and the bowls are finished by hand. Heads from the late 90’s were all done by hand. The work is a little more conservative from about the early 2000’s on. Likely due to minimize striking water from poor castings

I noticed the CNC ingraving on mine when they were off. Thats why I asked. They were purchased 8-17-2000.
Thanks guys.
