I've got/had all three. I think the 103 is better in a 124 body. The SDL is the world's most wonderful car. The 123 with a OM 616/617 is very reliable and inexpensive to operate. I'd RUN FAST away from a recently welded head. Unless you have a good head and don't mind changing it. At 12:

Ed. Valve guides are replaced with the head off. It is theoretically possible to pull the guides with out removing the head but most likely the valve seats will be worn and would no longer be concentric with the valves and guides. The guides are driven in and usually have to be reamed. Replacing
