What brand of pistons? Wisecos? What kind of compression are you running? Dual or single cooling? What type of ignition? All these factors will determine what type of piston clearance you can use.

Wiseco pistons, dual cooling, pump gas compression. MSD TL ignition, full spectrum 48mm carbs, B pipe.

For your setup I'd run 0.0055" to 0.006" piston to cylinder wall clearance. If you were running Pro-X, I'd run 0.005" or so. Be sure to warm the engine up first to avoid a cold seizure.
