Hello everyone. I need advice in choosing the correct pistons . I'm in the process of building aturbocharged 1326cc bigblock engine. I'm using a kz1000 bottom end with a 1984 gpz1100 cylinder head. I know that with the bath tub gpz1100 cylinder head it will drop the compression ratio 2 points. I want a comp. ratio of 8.5 I have been told to use a kz 10.5 ratio piston to make it out to 8.5 with the gpz1100 head, but i was wondering if the kz piston would match up with the gpz1100 combustion chamber ?
Experienced knowledge needed please.
