360 Magnum Crack....head bolt to water jacket

Purchased this used long block and when I was cleaning it up I noticed a poorly executed thread repair and a crack running from it to an adjacent water jacket. The threadsert sits up above the deck. How a cylinder head sealed I have no idea. No signs of moisture in the combustion chamber and the gasket that came off looked fine.

My question is was the thread repair put because of the crack or did the thread repair cause the crack.....?

If it passes a pressure test would y’all run it?
