I have installed thousnads of TRW valves which is part of AE Federal Mogul which also has their own valves. Used IV in the past but found QC not as good, valves getting thru with nicks in the stems etc. Never had an issue with any of them. Id be more concerned with the valve guides and finish of the guide.
