If you were to go for the copper head gasket as TE72_Turbo said it is a good idea to get the block o-ringed. I got my block o-ringed for under $100 for a 6 cyc. Or could get the head oringed. Not sure if you need to strip either the head or block down eg pistons out etc, I dont think you would have to tho. Goood luck & let us kno which way your going.
