Time to get working on the one spare I have. Was able to remove the intake pocket intact. Then the exhaust valve could be removed. Next was the 100 year plus installed exhaust guide. Lots of kroil, time, heat, and patience led to the guide being removed unscathed. All going good.

#Katherine, yes the valve guide is located in the “center” of the head. Its function is to align or guide the valve. This ensures proper sealing. Galling is common on older machines. He stated that it was removed unscathed, which is very good, saving time and effort.
