Got a new head from Sonex, and got the OLD head, that I accidentally punched a hole in the exhaust port of when cleaning up the abundant casting flash, back from a professional welder, so an interesting comparison of the Circa 2001 CB Performance based heads to the 2020 Empi based heads. The Empi (current) heads are on the bottom of picture from the intake ports, and the top of the picture from the chambers, and have much less casting flash, and a higher surface finish. They are the nicest aftermarket VW heads I've ever seen.
