Now that the valve and cylinder head are nicely cleaned up, the valve is noticeably eccentric during rotation. This is most noticeable as the black crescent that appears on the edge of the valve when the "6" is rotated 90° clockwise. When tested, this valve pulls 0.5" of vacuum.
- Is this visible lack of valve concentricity a cause for concern?
- Would it cause any kind of damage or premature wear if it is pressed into service? It might be worth mentioning that I intend to use this for cylinder head for occasional drag racing.
