Favorite Big Block Roller Rockers

I've read that iron and steel are the best way to go for street use, at least due to durability.
In 2013, Mancini racing had these aluminum rockers that were supposedly made by Harland Sharp even though HS put no identifying marks on them.

I don't drag race but I do put street miles on them. The lash doesn't grow and they are still in place.
