Om 603 cyclinder head - goose_ss4 - 10-15-2019
Looking for a good cylinder head for my 87 300d om 603 with 722.3
Have a he351 and 7.5mm pump. Runs good but I have a 14 head with a 180k on it. Would like a 17 or 22# head. Know these things are getting hard to find parts, but please let me know.

Hows that 722.3 holding up? lol I have a #22 head that I was planning to list soon. I'll throw in a free 722.3 to. You may need a spare with that turbo/pump setup
The head is in good shape, doesn't pressurize the coolant system, no noticeable cam wear, etc. . I pulled the motor though because I have low compression on cylinder 2 with a little blue/white smoke. A leak-down test suggested a boo boo on the cylinder wall or rings. But I still need to remove the head to confirm everything with it is tip top. I bought the motor/car in this running condition, and unfortunately don't have the history on it.
I'm located in Ohio though, which may be a deal breaker for you. Figured I'd reach out nonetheless.
