If he goes flat top with a .027 gasket he is only 12.88 for 4.040 bore. I have made the change from the 20ish cc icon to the icon flat top. Hard to keep it under 12 to 1 with gaskets. I’m .010 in the hole and 62 cc chamber? .027 gasket, Comes in around 12.2? If he is really zero deck and 60cc thats a BIG gasket to get it to a street friendly number.
