Exhaust manifold broken bolts

[Lead_sled]

So, I’ve found while searching that this seems to be a common occurrence.

I’ve got the last 3 bolts broken and have of course a squealing noise. Classic symptoms it seems. My question.....what’s the best method to get the broken bolts out? Remove manifold, drill guide hole and use backout bit?

I can only imagine that they’re going to be pretty stubborn to get out. I’ve also run across a kit to get these out, but not willing to pay several hundred dollars for it unless necessary.

And I’m sure it’ll be wise to put all new bolts, spacers, and gaskets to all that is broken loose.

Suggestions?
