I have a 1972 with the 1.7. Do the heads have to be fly cut if I go with the AA 93x66 cylinder and piston kit? I know they do if you run the 96x66 but I am unsure about the 93x66. Thanks

I thought fly cutting was trimming the surface where the cylinder mates to the head chamber. To put 96 mm p's and c's on a 1.7, the diameter of the heads have to be enlarged to fit the larger diameter cylinders....(like you stated).
