Considering the whole new block has maybe 10k on it, I'd hope it's fairly flat. I would expect the head would warp well before the block would. I will check it though when I pull the head. My roommate has one of those "certified straight edge's" up in his room that I could use.

And if my block isn't perfectly flat, well right now there really isn't much I can do about that. I'm not pulling it out. (waiting for a "that's what she said" remark)
