340 mismatched heads?

Sorry it took awhile PT after my knee surgery has slowed me down. I dug out my "Z" heads, and took a few pics on my phone. I bought them about 12 years ago at a swap meet in Spokane for $200. They pressure checked good, and I slipped a set of 2.02/1.6 stainless valves I've had laying around. I'll take more detailed photos if anybody's interested. I'll have my son help me upload the pictures I took, I'm old and suffering from CRS. I'm not really attached to them, so if a member here has to have them, I'll sell or trade them for any reasonably offer.
