Being price is within $100 of each other.
Considering a turbo will be used in this application are these heads about the same?
Which one has more potential later on if porting is done?
440source has been around a long time and I'm familiar with the name. (advertising works) But the ProMaxx heads have the bling bling sound and seem "new".
