The hyper pistons are fine for a N/A street engine. By street I mean a engine not built for all out racing, say, not turning over 7G. If you're going beyond that you want a stronger piston (and rods and wrist pin). Also if you plan to use a power adder then you need a higher quality piston that can handle the abuse. Power adders build allot of heat, and can stress the pistons around the ring lands. but the thing that seems to kill pistons is that detonation can break a piston and you're more likely to have that happen with Boost or Nitris then running N/A.

Most pistons are a few thousandths in the hole, again killing your quench efficiency. DO NOT have them above deck without accounting for it in your head gasket selection.

Just be carefull with the zero deck block, You must checked everything closely! When you deck the block to zero it can cause piston to valve clearance issues.
