Icarus rocker boxes

This is one of the rocker boxes for "icarus". The original aircraft box's were pretty cheap stamped steel. I wanted to make a 2 piece box so i could take the top cover off with the motor in the frame, to inspect the top end. I also needed a way to attach a top motor mount, because there wasnt one when the heads were in the original boxxer configuration. You can see the mount on the left side, attaching it to the downtube. I also had to tap two oil returns into the valve guide area, because, once again, this head was never designed to be upright! Hopefully the oil will return to the case through gravity and/or crankcase vacume.
