@backyard_shenanigans: I’ve seen it all but the one thing you need to do is clean the coolant and debree out of the threads before torquing heads bolts down. Comment other mistakes made#snapon #techtok #shoplife #gm #enginebuild

Courteaux :

That’s one thing they taught me in automotive class in high school. Dort cause it can make the threads bind up making it hard to turn possibly mess up threads and coolant/water because it has no where to go so it’ll build up pressure and then shooot through the bottom causing a hole in the block or head.
