Alright, this might be a dumb question.... I've had these heads kicking around the shop for a looooong time, and funny, I had never noticed the position of the water outlets. Looking at the current offerings, the water outlet is parallel with the mounting surface, mine are cast at an angle.... I'm wondering if there is any functional reason for this? is it just that these heads are an older design? Inquiring minds would sure like to know!!
