WOW ya really blew that one, Hogged it out pretty good did ya
Clean off that JB weld and Hog out that hole one more time to prep it for AlumaWeld solder
Fill the hole with AlumiWeld solder, resurface and drill and tap new threads.

But maybe ya should just but a new Engine, since ya couldn't put in a Helicoil
