The latest standard Stealth offerings from 440 Source come better bowl prepped and have better OOTB flows than we have seen previously.

I'm actually about to buy a pair of these so I'm interested to hear about any improvements in quality. In the past I've read that Stealth heads will need at least a valve job before being ready to bolt on and go. How did these ones look? Are they more capable of being a ready to run head?

Thanks!
