from what i can tell, they aren't cnc ported, but have the same effect as porting by using a different casting or something...

The "As cast" version is not CNC'd. The castings are however based off of the fully CNCd head. These heads are making great numbers and it does not take much at all to get them to run as good as a CNCd head. They are defiantly the best piece out there for that kind of money right now.
We do carry them and can have them out same/next day.

Thanks,
Leo
