I've never dealt with fly cutting pistons, but while pulling a motor apart i noticed that the fly cuts from piston to piston are noticebly different sizes. I would think this would effect compression and AFR from cylinder to cylinder.

Is this correct?

Are you sure it is flycut? or is it valve to piston contact?

The pistons are fly cut they are just noticeably different from piston to piston.

They should be the same in size if done properly. Post up a pic.

I will have to snap pics tomorrow morning when i yank the engine. I will post up then. I didn't think it looked right but like I said first time dealing with them.

Should they be? yes. If they are off a bit from one to the other are you going to notice it as an issue? no. A flycut is only a CC or 2. If you are off by one here and there, you are changing the compression in that cylinder by 1/5th of a point. It will still run fine but it's sloppy work.
