as said not as cheap as u think when u have to things like jimbo said, plus by the time u buy engine gaskets fluids etc!!

Plus u may find the valve guides may be damaged and need replacing too, then when taking the head off may be damage to it or its been skimmed to fuck etc etc!! endless list lol..

The other option u have is to keep ur eye out on a whole engine on here for sale, im sure some of the breakers will still have some coming their way now and again!!
