Fidanza Flywheel vs Dual Mass Depth

[Torchred96]

I know there's a lot of Fidanza threads but I couldn't find what I was looking for.

Purchased a Used aluminum Fidanza which came with the pressure plate and disc that it had been installed with. Looks to be in great shape.

I noticed that the original dual mass and fidanza are different heights when sitting on the bench flat. So I measured the difference in width (front to rear) and there is approximately a difference of .120" with the fidanza being thinner (ring gear to face distance), that appears NOT to be from wear. I made a second measurement with both flywheel's clutch side down on the bench and measured the distance from the flywheel face to the front of the bolt holes (facing the block) and the difference was approx .080 which is a little better and probably the more applicable measurement since it measures the distance from the crank to the face of the flywheel no? But the question remains:

1. Will this difference cause a problem with clutch pedal travel and will I need to adjust or change out the fork pivot because of the difference?

2. The flywheel to crank holes are recessed/countesunk. I'm concerned that flat washers won't follow the contour of the countersink. Do you think that is a modification or is that the way they come from fidanaza?

I read many threads about bolts but I didn't see any addressing countersunk holes

thank you.
