I've pondered this for a few hours and came up with the conclusion it might not be a bad idea for those so inclined to face off the flanges .

Case in point of several OEM Mahle cylinders I 've done there has been a slight difference in the flange thickness in retrospect to the machined face that meets the crankcase .

It might sound anal but a better thickness and fit on an enhanced compression engine would be benificial .

If you could get a tilt on the axis of the bolt and cant the head out of alignment it could theoretically pull the threads on one side .Highly unlikely but possible .

I don't think you could get a miss fit nor tilt the flange of the bolt that much no more torque than it gets but everything counts an enhanced performance engine .
