Cross hatching is for iron cylinders, not chrome or Nikasil...You want smooth so as not to wear out the piston rings...If you had cross hatching on a chrome cylinder the rings would not wear the chrome smooth, the peaks on the cross hatching would wear the iron rings out in short order...The lines you see in a chrome cylinder are the valleys left from the original machining operations...
Old gaskets seal just as well as new gaskets, why not use them ?
