I need to check but believe I have a Carter Weber carb on my setup. Looking at the Stovebolt Engine Co website, he recommends these for dual setup only but mine has been running great for several years.
I didn't have any problems matching the Fenton headers with the original intake manifold, and don't have any heating system on the intake manifold. Again with the electric choke, I haven't noticed any issues. But I also live where the intake manifold can heat up just from the ambient air temp. No need for heat in my truck.
Roller, I'll send you a PM and we can meet up whenever you'd like. I am not retired but will always take a break from work to take the truck for a drive.
