I went to pull off the coolant drain plug on the block, but the thing won't budge,

Need help please! The stupid plastic on the radiator broke, forcing me to replace it. While I was replacing it, I figured I'd do the whole maintenance, replacing a bunch of the cooling components. I went to pull off the coolant drain plug on the block, but the thing won't budge, in fact I am on the verge of rounding the whole thing. Any tips on freeing it up a bit?

If it will not come out with traditional methods, it may be best to leave it alone. I would suggest vise grips, etc, but there is not enough room to get a pair in there.
