The Stovebolt Site Forums The Shop Area Engine Shop Brand new head gasket burned up due to no coolant flow?

I also forgot to add that when I got the truck from my grandpa, it had a blown head gasket already.

I checked the radiator and it flows top to bottom just fine. I also pressure tested it and it passed. There is a bleed line on top that is constant. With pressure constantly applied, it would bleed enough to maintain 4psi+ no problem. I also check flow through the block and head and it was good.
