A long shot but it happened to me with the described symptoms: plugged Cats.

Well, it's probably incorrect plug wire positions on the distributor drive.
I assume this is a pre-1996 119 engine with dual distributors and coils
correct? I doubt compression is an issue. Cam timing is relatively easy to
check after pulling the valve covers.
I'm betting that it's the position of the plug wires on the distributors.
Check those carefully against a diagram. Note that some wires from the
right bank route over to the left distributor and vice-versa. I'll bet this
wasn't done.

I Have posted the message on the R129 list but since I am not a member of
the R129 list I fear that my post will not get through. Those few who have
transplanted the an M119 engine to their W126 SECs might be able to offer an
insight.
Anyway, the problem is that my mechanic is working on a R129 that needed a
valve job. After he refitted the heads back, the car in question has no
power at all. It starts and idles fine but has no power once on the go, if
the accelerator is floored ---- no power. I will be visiting him next week
to personally drive the car and see what could be the problem and to help
him do a bit of trouble shooting.
A few things already in my mind are to go over the cam timing, correct plug
wire fixing and a compression test. Any other points that come to mind would
be welcome
Thanks in advance.
