What should piston clearance and ring gap specs for Vertex pistons be? Same as stock?

If it's going in an engine with a higher compression head and a pipe, I'd set the clearance around 0.004" to 0.0045" and the ring end gap at 0.016" to 0.017"
From Vertex:
We recommend .060-.070mm clearance…….same as .0025-.0030”

If your engine is completely stock those specs will be fine but most engine builders will add some extra clearance for added heat from higher compression, porting, race pipes, more ignition timing, etc.
