Mine felt like they were welded into the heads. But be careful (hence 2 hours), and drive on.

I assume soaking the bases with WD-40 for a while first is the best pre-removal approach?

WD40 is a very good Water Dispeller but a lousy penetrant.

I'd recommend an excellent penetrant but the shipping would kill you, try PB Blaster.
