Suhr Floyd block question

[RG955TT]

There are 6 holes in the block on my Floyd trem. Which am I supposed to use to anchor the 3 springs? 3 are normal and small and the other 3 are right next to the normal 3 but are slightly larger with the top chamfered or rounded off a bit. Thanks for any help.

They are lock screws to hold down the springs
Generally never needed and adds length to the block which had hit the backplate.
