Probes are a good bang for the buck forged piston.
They have an FPS piston (pn P2600F), which is a high silcon, low expansion forged aluminum, like 4032. The piston has a 1.340" compression height, so keep that in mind if you're going to resurface the deck of the block. With a 9.240" deck, they would already be .009" out of the hole.
