Exhaust manifold trouble

Exhaust manifold trouble
HELP! I am tearing apart my 455 and when I took the pipes off of the exhaust manifolds 3 bolts broke off and are stuck in the manfold. The bolts are broken off flush with the manifold surface. There is about 1/4" of the bolt sticking out of the opposite side of the hole. What would be the best way to get these out? Should I try an EZ out, or should I drill them out with a larger drill bit and put a HeliCoil in? Someone at the auto tech center on base said I should heat them up with a torch and try to get them out the back of the hole with a pair of vise grips. I think the bolt would just smash and the threads would get damaged. I have never had any luck with vise grips. I will take some pics tonight if I get over to the auto tech center.

Or you could just buy another one from someone on R.O.P. dirt cheap.
They probably have piles of them from header swaps.
Think about it, if it's going to take you 3 hours to mess with plus a mapp gas cylinder.
Assuming you want to pay yourself 20 bucks an hour for labor, $60 bucks is guaranteed to snag you a good mani.
