your gonna need rings, another head gasket, and then you need to take out your crank and inspect it and the rod bearings, then go to the machine shop and have them turn the crank if its damaged and get them to order you a set of main bearings/rod bearings it will probably run you about 500 or a little less you will also need a rehone possibly. You could leave the pistons/rods in the block and pull the crank out but i wouldnt really recommend it.
