Go with a kimpex "spx" dual ring piston best bang for your buck . Its really up to you on how much your wanting to spend. be SURE your ring END GAP is within spec when installing new pistons . Also check your squish as this is important also .
10 min on one and 1500 on another. Squish is the the space between the piston and the head. U tube has some good videos on how the measure this. And don't go kimpex. It's cheap for a reason. MCB or wossner make a quality product.
