Replaced what we thought was a blown head gasket on a 1989 535i, after having the machine shop pressure test it. They said it was OK. Got it all put back together, but still coolant in the oil. Paid a mechanic to come out and do a compression and leakdown test and he said it could be the gasket or the head. Took the head off and back to the machine shop, and they found a 12" crack in the head.

Now, they are looking to find a bare head, but I want to make sure they are giving us a fair price on the cost of the head, and not charging $$$$$$$ for the part to recoup the labor of swapping everything into that head.

So, what is a good price for a bare M30 head? What years of heads from 735i and 535i cars will work? Does anyone have a head for sale?
