There was a whole technical debate on the topic on supraforums.com, and numerous people (about 10, at least), posted in saying they had the head gasket re-torqued and still blew heaps of head gaskets. A guy i knew here who is a mechanic in a performance workshop blew 4 headgaskets running on that torque. It reduces the chances, and i'm not saying it's stricly inevitable, but i would count on it happening. He then converted his 89' supra to a 1jz. but anyways safest bet is to go with a metal head gasket, apparently HKS make a good one for the 7m.

You sound like you read a lot but you don't actually have the nouse to sort out what should be ignored (most of it) and what is worth taking in (very little).
A lot of yanks seem to expect that they can run 4.75 bar on a stock head gasket with a retorqued head, and bag the motor when it blows a head gasket.
If the motor is healthy and well maintained, retorque the head bolts. You will have absolutely no problems with the head gasket as long as the car is kept in a standard or mild state of tune.
Oh, and if that guy blew four head gaskets then he's obviously just like 99% of car people - doesn't know what he's doing/talking about. Clearly the head or block must have had imperfections or the car had other issues that caused the head gasket to blow on regular occasion.
