If the camshaft was 180 degrees off, there would be no problem whatsoever with the valve timing. (The crankshaft being 180 degrees off would be different.)

To illustrate, let's say the the #1 piston is at TDC on the compression stroke. The head is removed, the camshaft is rotated 180 degrees, then the head is reinstalled. The #1 piston is now at TDC on the exhaust stroke. Valve timing is correct. The injection timing is 180 degrees retarded.

Sure about that?
