It is a no no to torque the head down in the manner that you are talking about. As Jason has said, if you over tightened the nuts you could of damaged the head gasket. If you tightened un-evenly, you could of warped the head. When tightening any engine related bolts, it is important to use a torque wrench and torque the bolts to the designated amount specified in repair manuel. On a head, sometimes they even have a pattern for sequence the bolts are suppose to be tightened. Ussually in a star pattern, or inside first working your way out. I don't have a manuel for a super M so can't tell you the torque spec, nor the pattern if there is one. If I was you, I would loosen the bolts and retighten correctly. If damage has been done, you will notice compression or water leaks and in either case you will need to replace the head gasket, and if head is warped it will need to be plained to correct the surface back to being perfectly flat.
