Well, look what we have here!

The first set of valves I had made were from Donovan. After a year on those valves and some more learning, I went with custom Ferrea valves because Donovan quit making valves.

FWIW, I used a 55* seat on both sides and a tulip valve for the intake and exhaust. Maybe the people who still haven't learned that there is power in steeper seat angles and tulip valves are why their heads flow less than mine. The flow curve was nice and smooooooooooth and the ports were very quiet.

I *THINK* I could make some gains if I used a 1.500 exhaust valve and just use a 2.08 intake. Obviously, if I was motivated, I could move the valves over .060 and maybe use a 2.125 and 1.500 valve. Of course, you start running out of port and I'd have to do some welding.
