How important is it to resize your rods when you install new rod bolts?

I'm asking because some people are telling me that I'll risk spinning a bearing if I don't get them resized. Keep in mind, these are cap-screw bolts, not the kind that need to get pressed in/out.

The last thing I feel like doing right now is removing the rods and paying to get them resized. All I'm planning on doing is popping the pan off and replacing the current bolts with new ones.

 

No input huh? Good. This is one corner I'd love to cut

 

No need to resize for capscrews.
Mandatory for pressed in bolts.

 

Should not be any problem.You ended up buying Crower replacement bolts right (same as whats in there).

Thanks guys. And yes, I bought direct replacements from Crower.
