Cylinder group height's??

Not knowing cylinder's had group height's I purchased two used 2.0 biral cylinder's. It appears these are group height 6 where my four original are group 5. Can't determine any measured differences between the set's, so what exactly do the group height's mean and can I mix the 6's with the 5's?

I'm guessing the differences are incredibly small, but may cause a problem with even torque across the cam towers if the group's are not all the same. Are 5's and 6's close enough to not worry about?
