So after finding a valve seat in my cat, me and a friend who is a mechanic swapped my 5sfe head, torqued all headbolts down to specification, resurfaced everything before putting new headgasket on, etc. after finishing it ran great for all of 10 minutes then started overheating and when we stopped and pulled the radiator cap off coolant was volcanoing. I'm still a noob/learning a lot of this stuff and I know it is a broad question but does anyone know where we may have went wrong? from what I've been told it is probably the new headgasket being blown but I want to know if anyone else has experienced this before i waste money/time sending the head in to get milled. Any help is greatly appreciated

We'll start with the easy stuff first, did you let the coolant burp? Did you replace the thermostat? If it were the head gasket you should have oil/coolant contamination or white smoke out of the exhaust.
