What are some of the advantage of having adjustable rockers over non adjustable stock iron rockers on a big block 440?

I swapped to adjustable rockers on a 383 i had in the early 2000. We did it due to the large cam the PO had installed.

You can screw up the preload and bend pushrods or wipe out a cam lobe?

Thanks guys, that makes sense it helps be consistent across the board in relation to preloads and such, does this trnaslate into any performance gains?

No not really , your stamped rockers will have the same preload consistency across the cylinder bank. But the adjustables will probably have a closer to 1.5 ratio over the stock stamped rockers so you'll get more performance that way . But just like when running a solid cam , which is why you need the adjustables , there has to be on 2 or 3 threads showing under the rocker. You need the CORRECT length pushrods , it's not going to be cheap to make the switch if you really don't need them .
