Looking for some advice, got some very corroded header studs/nuts. The two in the middle the nut has actually disintegrated and flakes away however the stud still feels solid. I plan on swapping them for some stainless studs and nuts, i'm going to soak in penetrating oil and use a blowtorch before trying to remove and hopefully this won't shear the studs and will loosen. Will also remove radiator before attempting.

Any additional tools i might need? i'm planning on using a socket wrench on the nuts that still have their shape and the bolt remover sockets (with reverse spiral flutes) on the really corroded studs.

Nut splitter might be handy.

It sounds like you've got it well planned out, the blowtorch is definitely your best bet to free them, I don't think the penetrating fluid will do much unless you're just using it to cool the studs.
Maybe a dremel would be handy to slice the nuts with a cutting disc or even just to clean off the rust with a wire brush to give the socket the best chance.
Let us know how you get on

If you end up getting nut splitters, get decent ones. I bought a set from Machine Mart to get exhaust nuts off a car and the guide screw sheared on the first use, must've been made of cheese.
