locking crowns on main bearing caps

I pulled my oil pan off of my 3.0 verde block that I hope to install soon and I noticed that the machinists that assembled it did not use locking crowns or locking tab washers on the main bearing caps. I have a spare parts 2.5 block with lock crowns and tab washers and I am wondering if I should use those parts on my 3.0.
Some say that alfa put them there for a reason, others have told me that they would never re-use hardware like that, they would only install new pieces.
Does anyone have an opinion they could share?

Thanks

Currently planning to use the crowns from the 2.5 unless someone thinks that it's a bad idea.

My 3.0 didn't have them. So i rebuilt the engine without them. I get the feeling some v6 engines have them and some don't... :|
