AFR Heads

PRH said

What are those going on?

Bought as bare or assembled heads?

If bare, and you’re going to use other than AFR valves, you should do a little build-up thread.

Do the valve seats look like they were done on a Newen CNC single point machine?

They are not earmarked for any particular build yet, my supplier sent them to me because there new of course. As far as valve job, I'm not sure? I use goodson 3d cutters in a TCM25 machine, but I cant really determine how these were done, but the bowl blend is obviously CNC, not by hand or bowl cut. Supposed to use LS 8mm valves
