Works for both Axys and Patriot exhuast valve assemblies.
 
This tool is to align exhaust valves to the housing so they are square to each other and can easily go into the cylinder.
 
It is critical that both lower exhaust valves are parallel to each other when secured to the tie bar. If the lower exhaust valves are not parallel with each other, the valves may scuff the cylinder slots during valve travel.
