What? Your cylinder heads are not done?
Not on this head as its just for testing purposes. You can see the how the the guide being slightly cocked has influenced the de-shrouding cut of the valve job as it didn't quite fully clean up on the long side. On the actual heads I run a cartridge roll down the that side of the inside of the valve guide hole to help relieve the uneven pressure on the guide.
