I feel your pain dude! I am having the exact same thing happening with my truck right now. I did the head gasket, I did the radiator cap, I did the new head. So when all else failed I looked in the repair manual... in the troubleshooting section it says that when this is happening that you may be experiencing radiator cap failure, head gasket failure, cracked head, or cracked block. Time for me to test my block. I have had 2 of these heads crack on me in the past for no apparent reason and when I go scrapyarding I see alot of them that are cracked in the same spots. Hopefully you have better luck and it is just the head gasket or something cheap like that.
