As far as nitriding is concerned, it seems to be a safe process. We measured
a slight warp at the bottom of one of the lower legs on the front

housing but

I don't think it was caused by the nitriding process since the other side of
the leg was perfectly flat.

I have to believe that the clamping force of all those rotor housing bolts
would flatten out any minor warp.  How much, I don't know.  Its just not as
thick as, say, a cylinder head or piston engine block.  I would think it
would be pretty easy to measure the deflection under load from the tension
bolts of the rotor housing, but I don't know off hand the modulus of
elasticity of cast iron, or how to figure it, especially considering the
water jacket hollow space.
