Probe (or even Diamond, Mahle, JE, etc.) forged pistons would be a great choice.
Don't worry about excessive clearances like some of the older forged pistons used to run. Forged pistons these days run around .0045-.006" clearance depending on the brand and material. Your cast stuff usually goes at around .0015-.002".
If your block has the correct clearances, you will not hear the forged pistons....I promise.
