W906 injector seat cutting

[nemesis0124]

Hi
Just after some advice, ive got a w906 311 2.2 sprinter, ive had to change the injectors but having problems with them sealing properly.ive noticed their is a slight dome to the injector seats and washers but cant seem to find a cutter to match. Would cutting them flat and putting thicker flat washers be an idea. Or is that a disaster waiting to happen? Id happily cut the original seats if i could find or make the correct tool.
Thank in advance for any info

I bought a universal tool from eBay for £13 that I've been using for years and has 5 different cutting sizes. Get the correct washers from Merc as they compress when fitted.

Is the 17 x 17 angled cutter that fits the sprinter?
