Question about Garden
We soak the cylinder heads in hot oil for several hours to get the head heated enough to use a a specially designed tool to remove the valve guides. (see below) Even then there is the possibility that some re-surfacing / material build up is required that will result in the valve seat having to be removed also. It will be nearly impossible to remove it in someones garage without runiing the cylinder head and valve seats. Most automotive machine shops will do this for you if you carry it in. I do recommend that if you do take it to a machine shop that you have the valve seats re-ground. We had all of the tools to do this but never removed a valve guide on a cold cylinder head.

All I will say is one wrong step and you can easily have the need for a good machine shop or a new head.
