Carburetors & Brands of Fuel

I have a 604 with an ATM carburetor that my motor build put on the motor and I run VP X85 with it. I have never heard of them until I looked them up, they are out of Kentucky. Would there be anything to gain by switching to a Stealth or a Willys Equalizer carburetor. Or would there be anything to gain by switching to Base R85 or Base X04. I think the X04 is Base's version of CHP. I have a set of Beya headers would it be worth switching to a set of Pro Fab headers.

there a reputable company , if your carb is tuned properly , i doubt you will gain anything by switching , as far as headers , IMO , you have the best already .....
