Leaking head gaskets sound pretty likely.
With coolant temps at 195*F (100*F ambient), I get 9 psig typically. After venting mine and running it hard for 100 miles the most I see is 2 psig (normally 1 psig) and that is with the coolant at 205 degrees (coolant pressure will go up about 1 psi for every 8-10 degrees on a system w/ proper coolant level).
