Has anyone had any pushrod clearance issues using a 1.6 ratio roller rocker with X heads? It seems I need to open up the pushrod hole in the head to allow pushrod more room for the adjusting screw ball to seat in the pushrod cup. Is this a common fix for running 1.6 ratio rockers? Also I have posted a pic of the roller pattern on the valve tip for the 1.5 roller rockers. Does this look to far toward the outside? My plan was to use a 1.6 on the intake and a 1.5 on the exhaust.
