When going from bolts to studs in the main's, is it necessary to have the main's align honed?
Wow me too and about 4 buddys changed and never had issues in past 20 yrs...pray tell me how it would affect the caps/main/brgs.if they were the same ones that came off engine and same sequence other than stud is no doubt stronger than bolt and that may be debatable..Crap....I have been running my 440 for over 20 years with studs and didn't have the mains aligned when I changed.
I am not sure why it would be necessary. I don't believe changing to studs would affect how the main cap fits in the saddle of the block. But I am not an engine guru.
I have done many through the years and not even worried about it.
My take on it is simple. If a mild motor is together you wouldn't bother to put studs in it, but if you're building a motor where studs are considered necessary the engine should be blueprinted and that should include the main bearing bores...
Yes, have it line honed. Also check the clearance between the stud and the holes on the cap as bolts are relieved and studs aren't, and it will often interfere and bind, causing distortion.

Just cause you have switched and got away with it doesn't mean that is the final answer. When you add studs to the mains why not have it checked after torquing the mains. Cheap insurance I'd say.
