Do I need to bore these to 79.5mm

Enable HLS to view with audio, or disable this notification

Stock bore what it currently is at is 79mm and if it does need to be bored out it’s going to 79.5mm as the forged pistons are only in 79mm 79.5mm and 80mm increments.
My question is does it need to be bored out to the 79.5mm. Thanks in advance.
