Thanks for all of the help.
I located a very close replacement at Diamond Wire Spring. Since the quantity price was quite a bit less than the price for 8 I have ordered extras if anyone needs them for a rebuild. They will run $5.50 each plus shipping. I also had to have retainers made, which should be replaced along with the springs if you want to make sure you don't have issues with the valves later in life. They are $11.00 each plus shipping. I'm not making money on these, just asking what I have in them.
The machine shop also located valve guides that are a very close match to the originals. I'll get the PN and vendor from him in case anyone needs these as well.
I had the valves made by H&J Machining in Carrington, ND. I highly recommend him. Fair prices and he does a great job. He also stocks a lot of old John Deere engine parts.
