Distortion is down about an inch but I need to do some more measuring.
I plan to use OEM bolts so I need to install them on this torque plate to see if they pull the bore less. If so, then I can back off the stud torque a bit. That's what I meant. I'm not proposing less clamping at assembly, rather less clamping for the honing operation. And I don't think I need to go all the way round. With all the engines out there running with .004 distortion, mine included, surely if I left .001 distortion it must be better. I haven't thought about ring gap yet.
I don't know the surface finish. It's from the fly cutter I posted above then dressed a bit with a file. Measures true, looks and feels good to me.
