Pistons

I'm going to use these pistons. They're used & are part of a disassembled short block I bought. Here's the description that Summit has:

If you're looking for pistons with an unbeatable combination of performance and value, Speed-Pro hypereutectic pistons are for you. These pistons are manufactured from FM244 aluminum alloy, which contains 16 percent silicon for greater strength and wear resistance. They're also molded in the latest permanent-mold technology to ensure the precise fit and tight bore clearances that today's top engine builders demand. They're ideal for use in high performance street, bracket racing, and oval track racing, and will work perfectly with normal ring end gaps.


It says "normal ring gaps." That's kinda' vague. What ring gap should I use? The engine is a 360 with a .030" overbore. Any recommendations as to ring type?
