Heads, which ones when....

If you read all the threads about aluminum heads and weighed the pros and cons you might just find a happy medium and decide on ProMAXX standard or maybe their CNC Shocker heads? From what I’ve read they come up: Affordable compared to the Edelbrock or TF’s, better machine work, parts, flow numbers IIRC, than the standard or CNC Speedmaster and Edelbrock yet cheaper than TF. Maybe someone will someday do up to date side by side of all them comparing casting, machining/valve job, parts, flow etc. Would be Epic!
