Yes and the valves need to be removed at the very least one has to be out no matter what. But best to removed them all so the head can be cleaned properly once all the milling/cutting and grinding is finished. To remove the bolt boss that is in the intake port. The top of the head will need to be machined as well and tapped for the pipe plug that will need to be installed.
