Had several that were real ulcer jobs, ended up not being able to find a correct head and then had to buy a new bare head, etc etc.
He's not lying to you, I swear they must have redesigned these stupid 60 series diesels every 500 cars or so, and STILL they never got them "right" until the 606, and sometimes I even wonder about those......

Not all 603 heads are created equal! Yes, the later heads were supposed to resolve the previous problem, but obviously according to what you say, they didn't!
Casting aluminum is an art! It's a merical that so many 603 heads came out without the usual "later down the road" failure!
Why?
Understand foundry/casting values for aluminum/aluminum alloy!
I just find it incredible that MB actually pulled it off with these heads and with attempts later to tweak them a little here and a little there, they had supposed to have gotten them closer to right, from #17 to the late, getting better with each tweak!
A bad #17 head may still be better than a good #14 head on it's best day! The taper introduced in the later heads does become a problem with early, or reuse of original precombustion chambers, but I have not heard of all other other head componants subjective to similar.
Can you elaborate?
