If it was me, I'd have the truck and replace the gasket, cost? Price of a Gasket set, a set of head bolts and a cam belt. Possibly (up to you if you do it) skim the head and re-seat the valves then sell on or just trash it into the mud as a toy.
It aint hard, just a b****y pain undoing everything and then putting it all back together again!
This posting may have been helpfull, on the other hand probably not... Either way, I may have had drink when posting it in which case it's probably not as helpfull as it could have been
Work safe, and remember all technical problems can be resolved with a hammer, the trick is knowing where to hit it and how big a hammer to use (I often find it may also help to have a spare bit in the shed to replace the bit you have just mullered

)
