My good friend has a machine shop out side of Philly. They have been around for 20 years. We have done a few 10v heads, 2 20v heads and they see alot of of 1.8 stuff. Pm me if you would like to talk about getting your head done. They do great work and we run it through on the side so its light on the wallet.

I would have to think 16v carries over. Just add another cylinder.

Really the angle is the same. You cut a three angle valve job at say 15,30,45. You can do a 5 angle job at say 15,23,30,37,45. Gives you better flow and less turbulence. You can back cut or flycut the valve as well to pick up some easy flow. The air rolls over the valve smoother. Then you can get in to valve margins. You can move it closer to the valve edge giving higher flow but less heat transfer(na heads). Or you can move it in to gain more contact to draw heat out of the valve.

Seems a little high to me. I would also have the manifold sides surfaced as well. I would think with out any parts you should pay between 500 and 600. I would put a set of exhaust valves in it and if you had any money let over go for upgraded springs and retainers.
