Another newbie question from yours truly!

Thought I would start my long-awaited polyurethane bush insert project today. I have managed to get the OSF one done and then went to do the NSF. I miserly invested in a 400W Impact Wrench whose maximum torque figure is 350NM.
This doen't free it.

Should this rating be enough to free the Subframe bolt on a 2006? Or do I need more grunt?

Do I start heating the bolt to try and shift it.

Bit concerned as I don't want to sheer the head off the thing and then look/feel worse than I already do!
