High CFM heads - What would you chose?

I had a friend that brought a set of aluminum Barton heads for me to check out years ago. They were uglier than heck with raised epoxy ports. The heads maxed out between 325-330 cfm. I recommend he not buy them as the epoxy was all dry cracked most of the way through the epoxy. At the time I didn’t realize that the 360-2 Indy head was basically a copy of those heads
