I have a PSI gauge hooked in with the Degas bottle. How I found out that my head gaskets were blown was the PSI gauge was hitting about 18 to 20 PSI before. Now the PSI gauge runs between 11-13. I've seen the gauge reach almost 14 PSI the other night, but I was really on the truck. Do you think my PSI is within the acceptable range of about 12 to 13 PSI?
It's unfortunate that you didn't insist on having the heads milled flat, because Ford's "acceptable specs" are not acceptable, but at least they used OEM gaskets.
Hopefully you won't have to do head gaskets a 2nd time... I found out the hard way (and expensive), after only 6000 miles the gaskets were leaking again, so the second time I had the heads milled and used OEM gaskets.
I think 10 to 12 psi is okay
