am looking for some exhaust valves for the early 2,0 liter engine.

These have a 35mm head and an approximately 112mm stem length, and are marked "ATE 3052" on the tip of the stem.

NOS would be preferable, although I realize that most shops blew out the last of their NOS 2,0 valves a few years ago. Still, you never know if somebody is sitting on a couple.

Used OK, but they have to be in spec. This means they have to measure at least 8.94mm all the way down the stem, the length has to be good, they can't be bent and they can't have pie-shaped burns through half the head, with liquid sodium leaking out and spontaneously bursting into flames upon contact with water. I know I'm asking a lot here.

Thanks in advance for any help with this.
