Well hell.

OK guys I figured I would see what suggestions you have before I go to town with my dremel and a cold chisel.

I started pulling things off yesterday and got it down to the head nuts. All the ones under the valve cover look good and weren't too bad to break loose. But then I was working on the four at the spark plugs and ran into a predicament.

Looks like that PO had taken a bad socket to the nuts and two are rounded off. Plus they are pretty nasty corroded. I have it soaking in lube since yesterday, but I don't think they are gonna come off without a fight.

Anyone else have to deal with this before? What would be the easiest way to get these nuts off?
