Unfortunately, cracked cylinder heads can be difficult to fix, and they are always expensive. the best thing would be to replace the cylinder head, but if the part isn't available, then that's a problem. It may be possible to fix the crack and keep the car drivable. I recommend calling some other shops and even parts stores to see if anyone can offer to a less expensive solution than replacing the entire motor. Sorry you're having such a mountain of trouble!

The bottom end of you engine is, what we like to call in the industry, bullet proof. It is a cast iron block and I have yet to see one that can not accept a rebuilt head. If there is no damage to the cylinder linings or pistons and no excessive play in the wrist pins or crank, then a rebuilt cylinder head should fix your woes. Cylinder head exchanges are readily available online for less than $1000. I have used www.headsonly.com a few times with good results.
