3000gt non turbo head gasket?

-Hello I have found a 3000gt online for $1300 but it needs a new head gasket put in. I was wondering how much a head gasket would cost and how much the labor would be? An also if its worth buying an fixing! ThanksIf it needs a new head gasket its not worth 1300, plus its probably been abused and has other problems, a new gasket would probably be well over a grand depending on the shop
