I see where you are at mate and to be honest you dont know what you will find when the head comes off, pitted head, warped, etc etc. along with all the other obligitory AAA parts you will need, crack pipes, water pump , stat, and not to forget you find the timing chain needs doing along with the guides, then clutch , on and on and on, a right can of worms.
Good luck mate , sure someone on here will be keen,
