Any experience with Speedmaster DNA rocker set for big block?

Wondering if anyone has experience with the Speedmaster Mopar Chrysler BB 383 440 Shaft 1.6 Ratio DNA® Aluminum Roller Rocker Arms Set:

I already ordered it, giving Speedmaster a second chance.

I am trying to RMA the stainless rocker set which had many manufacturing defects, but their support is way behind and their website says they're trying to catch up.  They are in L.A. but had issues before the wildfires.
