I'm suspecting a compression leak in head gasket. Does anyone have any other ideas? How do I confirm the diagnosis before tearing into the engine?

First, is the fluid being transfered back to the tank filled with bubbles....How about the fluid in the radiator...any small droplets of oil floating around in there? How about the radiators themselves, clear and free of debris trapped between the veins? How about the Waterpumb impeller....Have you removed the cover to ensure that the impeller doesn't have a broken fin? How about that Cap....Did you replace it with a 16 lb cap? anything less and your gonna overheat in 90 degree weather, especially if your idling for any amount of time or doing alot of slow tight stuff with no air crossing over the rad.
If you had a blown head gasket it would manifest its self either thru the exhaust as a white cloud of smoke or in the rad it's self as oil droplets or anti-freeze turning into foam from the air injection.
Also, you may want to drain and replace the anti-freeze with a product designed to handle the hot temps better such a s watter-wetter or Engine-Ice which I use and it does a great job....

I think I will try the water wetter. At the same time I'll take your advice and check the water pump impeller. But it seems like if it was overheating it would simply continue to fill the reservoir instead of blowing out the cap.

how is your jetting? make sure you not running that thing way too lean.
check the oil level, and see if there is water mixing in the oil?
make sure the area behind the raidator is clean as well, air has to have room to escape after it comes through the radiator. if there is debris clean it out.
