sorry ive been posting alot but.. im putting a new head gasket it my 06' and I took the head off. Me being a dumbass forgot to take the spark plug out, and loosened some of the bolts holding the head on cylinder first. They came out without any problem. But my question is is, could i have warped the head?? Could the compression in there do that? Both intake and exhaust valves were closed. I just remember hearing something about warping the head when tightening it down, but what about taking it off?
