you need the coolant tube that goes under the manifold, front timing cover gasket, head gaskets, head bolts(or studs which i prefer), new spark plugs(why not), intake manifold gaskets, i would also get a new water pump, and for a complete job get new timing chains and tensioners. also get some black silicone handy if you get the black stuff from ford you can get it in a caulking type tube that makes applying it a pice of cake. you will also need new valve covers if using the windsor heads. and then oil, oil filter, and coolant.
