Can't get exhaust manifold bolts off. Can you help?

I can't get my exhaust manifold bolts off. They are in bad shape. The 10mm is too loose and 3/8 just rounds. I have had the torches on them too! Can the bolts be cut off with a torch?? Haven't broken any. Can't get the bolt heads to move. It's an 04, original manifolds. I am working the driver's side. I can't figure this one out. Help to get this manifold off would be appreciated.

Also use a 6 point and some Kroil.
Heat, soak then let it sit.

Thanks for the help. The exhaust manifold is off. I soaked the bolts last night and used "a lot" of heat this morning and they all came out, no problem.


But I still have another problem. Check my new post, Exhaust manifold is out BUT I can't get the bolts out.


Thanks
