Question about Exhaust studs

Anyone have a good trick to get broken studs out of the bottom of factory exhaust manifolds, there is about a inch and a half left. Thanks

weld a nut to it. Or visegrips and heat. If its broken off even with or below the block you can use easy outs or reverse drill bits.

x2 try the vice grips first with some heat, prob should get it but if no get a nut and weld it then try again but with lots of heat just to be safe.

i have tried the vise grips so i guess the next step is alot of heat and some welding, and if that doesn't work the easy out. we will see and if that doesn't work i may just get some headers

Heat siezed it,heat will free it. Start by trying to heat the manifold only.(best as possible) The heated manifold will expand just a tiny bit(the hopefully somewhat cooler stud wont,as much). Maby itll be enough to get it free. After giving up on a stubborn stud,I have cut the stud off flush,then drilled it out. With a little lady luck on your side you may be able to re-tap the hole to the same stud size. With Murphy looking over your shoulder,you may have to re-tap a size bigger.(if room on manifold even will allow)

And by heat, we mean, HEAT! A dinky propane torch won't do it, you'll need a OxyAcetylene torch, and get it glowing red.

Even then, it may not work. I have ended up having to drill and tap them several times.

Do yourself a favor, and don't break a extractor off in it.

Ok... So I could never get the studs out and my practicality got the best of me on the headers so I found these for a great price $130 Shipped. We will see on durability. The casting looks good and it even came with plugs for the ports and also the heat riser.
