I clamped the Valve Guide in the 4-jaw chuck on the outside boss, and machined the inside boss and flange square and to the proper dimension so that both parts can fit in a fixture.

I then made a fixture to hold the Valve Guide / Valve Chest cover. The inner bore was machined in place, and a threaded rod with a plug that fits the raw Valve Guide casting is passed through the spindle. The back end of the fixture is threaded and the rod that extends through the spindle has two nuts locked on to draw the plug, and the Valve Guide, back into the fixture.

Then the flange and boss were machined. Not shown here is a releaf on the fixture to allow the measurment of the flange width.
