Well... first I removed all heatsinks form the card, then i used Precision Pocket Calliper Gauge (something like on this picture
here) to measure all details about the card. The PCB board was hight 0 for me. Then i measured height form the board to the top of the ram chips and GPU. Ram was 1 mm out of the board, and GPU was 2.2mm out. All other SMD components on the board were max 2.3 mm high. So i decided that the block should be 2.5 mm above the board so it would not touch any of the SMD components. Then I made pads for ram chips that are 1.5mm out and pad for the GPU that is 0.2mm out. And the same was for the back waterblock.
If you want a drawing of the card in Acad send me a PM an i can give you the link to see everything in detail.
PS: I didn't have the will power to do the mirror polish on the blocks because they already took too much of my nerves
