Normal
Total height would depend on the pump used, but at a minimum add around 21-22 mm on top of the 22mm block, so total would be around 43mm. the only issue with the lower pumps is that at that point the fitting choice will be restricted to low profile right angle fittings. Honestly the block could go abit lower but I don't know if there is an good reason to do this. The lower you go the more restrictive the flow path becomes.
