Since I replaced the head gasket, so I suppose it is possible that there could be some lack of seal, but it seems unlikely. I did do a compression test in which all cylinders were between 110 - 120. I am not sure any leak between cylinders would show in this test either, unless it was truly significant. There is no other indication of any head gasket problems, no contaminated oil or radiator water. I do get a small amount of water coming out the tail pipe on start up after a few days, which I don't remember from before on this car, but I believe it to be condensation. It seems like a leak down test might be the way to go before I pull the head, which would probably be close to the bottom of my list of things to do.

I did replace the thermostat and am finding now that all is good as long as I am moving. If I stop at a light, I can see the guage begin to climb (again, we are talking 70 degree weather). It will come back down as I get back up to speed.

I think my next step is to flush the block and to re-install my old water pump.
