Head prices keep on climbing. Part 5708760RX is a reman head. 5658294 is the part number for a new head. Looking at my cost it seems the new head is about 1600ish bucks more than the reman.

It does seem that the part number you were given is the most expensive CM870 cylinder head. I have a truck here CPL 8518 and the head new (5658283CUM) is cheaper than the reman one your were quoted. When I do a CPL compare between 8520 and 8518 they show the same cylinder head, camshafts, pistons, turbo, etc so I'm not sure what the difference between the two would be. So there certainly could be a cheaper OEM head that could be used on it if it ends up needing it after you follow Rawze's good advice on pressurizing the cooling system.

We haven't had the greatest run with reman heads whether OEM reman or a good machine shop reman. They seem to last about half what a new head seems to last.
