Hi,
Please understand that this is hard to estimate simply because I don't know what was damaged. It may have blown a head gasket, warped the cylinder head, and so on. Those two different things can make a big difference when repairing,
With that, I attached two pics below. Pic 1 shows parts and labor if it is only the gasket. If you let me know what all of the compression readings were, it may help me guide you better.
Pic 2 shows the cost of a new cylinder head and labor. I would suspect you could find a cylinder head that is re-manufactured for less money than an OEM part. Also, there is a chance if there is warpage, your cylinder can be machined which would be less.
Take a look at these and let me know if you have other questions. Please note that I am basing this on a non-turbo engine. You didn't indicated it was turbo charged. Also, there will be additional shop supplies such as coolant, new head bolts, and so on.
Take care and I hope this helps.
Joe
