That is awesome! I might have to look into getting some!Alright well I discovered something much better than PB it's called Deep Creep I sprayed both broken head bolts with it and about half hour later I was able to unscrew the broken bolts with my fingers! I doused the cylinders with the stuff and will try to move it tomorrow if it doesn't move I'm pulling the engine for a bare block rebuild get the block boiled and all.
