The aluminum ones were talked about quite a bit , pretty sure MRL was using them on his builds .

I have a MRL set, but yet to drive them. According to Mike they are good castings. Guides are crap. Buy them bare, replace the guides and buy quality hardware to match your setup.
What about the guides?

the numbers shown in the ebay link don't seem all that special
By the time you add guides, valves etc along with shop setup cost, wouldn't a set of assembled ProMaxx heads be the better bet and likely comparable in cost? There's some good info here on those heads and the quality of the castings, components and assembly

I don't know. That was info i got from Mike when I spoke to him about the heads. IDK if he frequents this board any more.
All the other engine builders my dad and I have worked with have said the Pro-Comp castings are good quality, buy them bare and build them with quality hardware. My dad has used a few 350 heads and a set of 302 heads. I have the LA heads. I looked into them for my 460 and those who build 385 family Fords considered them a fair stock replacement head that was good for the street crowd but fell very short when compared to other performance heads.
I think I'm $1200 in my heads, set up for my cam. I bought bare castings and sent them to MRL because he had the most knowledge of these castings and new what to do.
