From your pictures of the combustion chambers, they look to be 2.02 intake valves. Do you have any of the hardware, valves, keepers, retainers, or anything else that go with them?
I had the valves, springs, and retainers, but the machine shop said the valves and springs were out of spec and needed replacing. I bought a micrometer today, but and having a hard time finding where to measure.
