I bought them as an up grade over my factory steel heads. I would buy another set for a budget build.
the doug herbert heads may not be for everyone but for my applacation they work very well. as far the casting goes, they are very nice. I was suprised myself. ive seen some sets from edelebrock and they were down right UGLY. as far as the flow goes, i was just looking for something better the the stock steel heads. I had mine flow checked and they are way better then stock. I run AFR on my race cars so I do know the difference. but the herbert heads are ok for mild builds.
