I'm set at .059 cold.
Rads are in and I will be leaving here in the am.
Hope this helps
If you get a chance, do a test. While the engine is still somewhat cool, try the Jakes and see how they operate. Then after the engine is up to temperature do the same test on a similar grade if possible.
I found that the cold test that the Jakes worked significantly better than after the engine was up to temperature.
Based on that I changed the clearance to .055 and realized significantly better Jake action after the engine came up to temperature.
