Choosing pistons

Instead of getting differing opinions from the forum heroes, you should be calling piston manufacturers. They are the experts.

I would suggest, Ross, United Engine and Machine, Diamond, Arias just to name a few.

That way, you will be talking to those who make the pistons and can answer your questions with facts, rather than with opinions.
Just got off the phone with the manufacturer. They recommend the icon forged 2618 34cc pistons.
