Ok guys, I was on Facebook Market place and a guy 20 mins from me says he has a set of Yates C3 heads fresh from the machine shop. I wish I had the money but I dont. Here is what he wrote.
"2.17 intake valve and 1.59 exhaust valve they have DR425R springs to go with them. They’re fresh from machine shop. No rockers or pushrods."
There is a picture of them, they look nice. So if any of you are interested, pm me your questions or info and I can act like a 3rd party.
Not sure the add link will work but here it is anyways just in case.
