Main Studs??

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.
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..
