If you have 5 emulsion blocks and they are all open...that's not good.
A good starting point is 1 and 3 get .026-028 bleeds and block 2,4 and 5.
If you block doesn't have brass in it, make sure you measure the holes in the block. If they are .026-.028 you can leave them. If they are bigger, use brass set screws drilled to size in the holes.
