Even if you get rid of the stock Motronic (which won't work with those cams) and get some sort of stand alone system or carbs, you still have the problem of the piston shape that the CIS/Motronic cars have. It is a high dome on one side that channels the fuel to one side of the combustion chamber where the single plug is. This high dome will interfere with the valves on high lift cams. You would need to use the hemi-style piston with the deep valve pockets to use these cams.

This is why I am using the carb/MFI piston with the stock Motronic for my 3.5L. If I ever want to get rid of the Motronic, I would just need to change the cams and not the pistons as well...
