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".

dad has a set of the CNC ported stealth heads. quality was very nice and they have a pretty thick deck. I'm sure they would handle some boost I have them as well. They work pretty good on a budget.

I have a set of Sidewinders from Todd Marsh, they are on my 440 with an F2 Procharger. Runs 15lbs boost no problem. Had Larry Smith do some porting on them as well. Are the sidewinders in the same price and as cast flow range?
