Slight reworking of the standard v2/v3 cylinder head. The pad on the bottom is slight thicker than what you see on normal cylinder heads (2.5mm in height), this helps to correct the angle of engagement of the piston rack and sector gear. Comes with 2 o-rings are around the base for improved air seal. The shaft walls are slightly thicker with a smoother end to help prevent damage to nozzle orings.
