Like the guys are saying, there should be no slop. I think your F/C is leaking when you play E/B. I am guessing that if you close the E/B the F/C will still press down a bit more. Or, if you close both, there may be a tiny gap between the Crowsfoot and the E/B touchpiece.
The right hand F#/C# touchpiece and the right hand E/B touchpiece should both be touching the crowsfoot when they are both up, and when they are both down. They should also be at the same height when they are both up, and when they are both down.
The left hand levers are a wee tiny little smidgen sloppy because of how they move the connected keys on the right. The F/C lever is especially bad. There is also more flex. However, when closed there should be no slop, and you should not need to use your right pinky.
Assuming there is no slop: The E/B pad and the F/C pad can be at different heights, or they can be at the same height. In other words, the venting can be the same or different. The length of the "pad arms" are different, but so are the other mechanics. Depending on how the touchpieces and crowsfoot are set, the pads can close at the same time regardless of the pad heights. If the heights are different, the E/B pad is higher and moves faster. If the heights are the same, they appear to move at the same speed. (I think it depends on the throw of the F/C touchpiece and the position of the crowsfoot. This changes the length of the "controlling lever", which changes how fast or far the "acting lever" moves.)
I usually end up with the E/B being a hair higher, but almost even. I have found it will work with the E/B a lot higher, not that I'm recommending it.
