I start flush with about .5-1" clearance (depending on nst voltage, 1" for 
15kv) between primary and secondary (assuming you have a flat primary). The 
trick is to get it as close as possible w/o racing sparks or arcs from 
primary to secondary. Flush about as close as you can get (unless you're 
going for a bipolar coil), may have to raise the secondary from there.
