Tips for replacing ex manifold studs

[Brrrrp]

Anyone have any good tips for removing the exhaust manifold studs from the heads? I was going to just grip them with vise grips and twist them out. Should I heat the head with a torch first?

Thanks.

why, is the first question. best to let sleeping dogs lie, unless there's a good reason. they don't come out easy, and generally need to be drilled. that requires a jig, so the drill is dead center and doesn't go off into the aluminum head and create more problems.

As usually, I agree with JW...

Don't pull them out unless they are super-rusted.
