As far as I'm aware, the only two headgasket types made for the Supra are the standard composite facing steel core gasket, and the aftermarket multilayer metal head gasket. IMO, a graphite gasket would suffer the same failures as a stock composite gasket. If you're going to have the motor apart, have the deck & head surfaced and use a metal head gasket. ARP fasteners are reccomended and should be torqued to the spec provided by ARP and not the spec in the manual.
I am running out of money for this project I am having every thing resirfaced but I cannot afford a metal gasket right now
$90 for a factory gasket or $140 for a metal.. save $50 and you're there.

It's a bit more than that if it's done properly. Surfacing the head and block to the proper RA factor isn't exactly free.
Jobsupra, if you're on a limited budget, use a factory gasket, clean the head and block carefully, and just torque it to 75 ft/lbs. (Over the years we've determined that the factory torque spec is 20 to 30 ft/lbs too low).

I recommend not using any spray sealants. Surface the block/head properly and they are not needed. Jdub explains it well here:

I have build 100's of engines, both 2J's and 7M's and I have never used it.

Are you refering to that Victor Reinz graphite gasket? I don't think they make one for our 7m's.
