I'm poised to loosen the head bolts on my 4.0L, but the FSM doesn't specify a sequence for loosening, only for tightening. I guess that means the reverse of the tightening sequence would make sense?

No sequence for it. Just take them out as you get to them.

OK, cool. So it really doesn't matter for loosening? A few minutes ago I found a post in the XJ forum here where someone was absolutely definite that you *had* to use the reverse of the tightening sequence or else you'd run a serious risk of warping or cracking the head.
