Well the concept and ideas may be Don's, but does he actually have a million dollar CNC machine to do the work?

That's why I posed my question. Tony was and still is heavily involved with the CNC programming and development of the RAV head and does a bunch of Pontiac development behind the scenes that most aren't even aware of. So it seems natural that he would also be involved with the development of this new RAIV head.

I do like the fact that the ends of the heads are already cast like a factory head with a provision for a freeze plug and all the other channels in place. That saves me a ton of time machining Eddy heads to mimic the factory casting.

Freeze plugs in the heads are great until they pop out. There's a reason folks replace them with a screw in fitting or welded plug.

Most likely you will have add them to a head first, before they pop out
