How to identify OM603 /603 # 14 head?
I'm sorry to bug you veterans on this but I'm just not sure WHERE to look for this on my car.
I tried to search but could not find the answer.
For the record 14 is the bad one and any others are good, correct?
Thanks all.

Let me google that for you

The search on this site sucks. Use "site:peachparts.com:" after your search criteria in google.

#22 is the newest, most updated design... 15 and 16 are basically the same as 14... 17 and up are ok, but they still need to be pressure checked and measured for deck thickness... pulled heads could be junk keep in mind.

#16 are NA heads. You're not likely to find many in the US. Never heard of a #15 head but maybe it exists.

True, but if he's looking for a head, and comes across either of them... move along... not better than the 14...
