I don't see the point in that. You have the whole tab on the front block anyway so you should just ensure that the ram threading is the same length as the mounting tab.
If you're considering machining the tab down then do not go for less than 4 turns of the thread. Any less and you risk it eventually failing considering you're threading into aluminium.
Remember too that the ram has to be long enough to maintain the correct stroke length. You can gain by "turning" the caps so that the air goes in through the sides but only up to a point unless you want to get really fancy and custom make the whole ram such that it has true side ports and a very small chamber area.
