When the cambelt gives up or jumps, it usually forces the hydraulic adjusters out of their housings - i.e. fractures the head casting. Some companies offer a welding service but the clearance for the adjusters is critical, so I would be skeptical of that approach.

I've bought and sold a number of Volvos as spares repairs following cambelt failure and I've done it most ways. I would say the easiest and cheapest option is a second hand engine. The cheapest way of buying a cylinder head is a second hand engine (heads on their own sell for circa £700), then you have the cost of gasket sets etc. and I would say it takes a lot longer to replace the head than remove/refit the whole engine. In each case you would want to do all fluids and belts.

Their used to be sellers on e-bay selling second hand D5 engines including fitting starting at circa £2k.
