*Distance from the top of the cylinder bore to the ring groove location is 0.250
*4.350 targeted chamfer to 4.220 over 0.200 inches.
*Anything above about 0.750 lift loses chamfer for flow advantage from chamfering.
*Valve distance to cylinder wall after the chamfer depends on valve lift. We will be measuring this with the cam installed to see these distances.
