Main Studs??

I have been Machining and building 440's for going on 40 years, I OWN an Align BORING jig, as well as an Align Honing Cabinet CH100 Sunnen.

Aside from anyone getting "lucky" as Mains are pretty forgiving....

I have never seen a Main Bearing Cap that does NOT distort beyond my comfort level....
when switching from stock Main Bolts @ 80 Ft/Lb Torque with stock BOLTS...
to
ARP Studs with 110 Ft/Lb Torque using ARP Moly
In my experience, They ALL DISTORT in the above scenario !

You think it's "OK" , by all means you screw it together.
