head gasket repair

ive seen two supras in the want ad listed as parts cars, and all they have is blown head gaskets. i know when teh gasket blows, you have to machine the block to put a metal one on, but can you still drive the car? i dont want to pay a ton of money to have it towed to my house. and also, whats the acerage price of getting the block sanded? if i could just drive it to a machien shop and pay them to take out the block, machine it, and put on the new gasket, ill go check otu those cars. has anyone done this?

You can't drive with a blown headgasket, the car won't start. So don't think of it, have it towed.
