Best performing non offset Small block Mopar heads

Nope.
That was the first version from like 4 years ago.
Makes sense as his FB page is pretty much inactive, his website is down.
All this head talk here reminds me of the guitar world.
With guitars and amplifiers there is a phrase used to describe amps that are hand crafted, hand wired, small run offerings, high end offerings etc that are referred to as “Boutique Amps” Everything about them has been well thought out. Circuits optimized for a certain result or output. You have your Fender, Marshall, Mesa etc and then there are these Boutiques ....Victoria amps for example. You get the same type opinion/reactions to the brand names and the boutiques. No different here. Anyone can buy the Speedmasters, Edelbrocks, TF’s ProMaxx’s from a catalog ready to go, bolt on and roll or they tweak em/have them tweaked, or you go boutique. This Bloomer head is a boutique head. If I were inclined to buy a head like this there would be no need to tweak it as we have to assume all that’s been done.
Looks like a small niche head derived from the same castings as many other offerings.
