Tech Tip for machine shops installing seats in non adjustable Ford heads. After the new seat inserts have been installed and you're machining the new valve face contact profiles onto the new valve seat inserts; It's important to machine the seat profiles to the proper depth into the combustion chamber so it doesn't negatively impact: available valve spring installed height and/or final required pushrod length. The objective is to restore the valve stem protrusion height back to factory specification, no more or less. Many machinists like to place the IN & EX valve head more proud up into the combustion chamber by not cutting into the new seats deep enough but this can lead to problems with achieving proper valve spring installed heights and lifter preloads. Of course, most machinists are already aware of this however, it never hurts to throw the information out there for those who have not put much thought into the process.
