Do you have access to the cutter you used? Just measure the dimensions of the cutter then calculate volume. Adjust your dimensions until you come up with 2cc volume. Walla, there is the correct depth.

I didn't cut, those are forged Wiseco pistons.
Motor is allready all buttoned up and running.

I might be looking at some outrageous cam and knowing the depth of those reliefs would help in choosing the VEs and chamber size of new heads.

Do you know the free drop of the heads? You could go to TDC and measure the free valve drop minus gasket thickness minus the original free drop.

it all depends on how wide a cut you made and how deep...
