Ok at the last minute I decided to switch to a Holly Sniper set up (kit is supposed to be ready 8/21).
I asked FFR about the headers and they advised that there is "a threaded hole the right diameter/thread pitch (m18, 1.5) that the o2 sensor screws into".
Just checking with the builders if the FFR headers are good to go for an O2 sensor or should I consider another option?
Thanks in advance.

The new FFR headers with the ball swivel should get you all you need. The Sniper only uses one O2 sensor, so you may need to plug the unused hole. The plugs are easy to find.

I have a set of stainless silver ceramic coated GPHeaders for sale if you are interested. I had to switch to another set when I purchased the Gas'n sidepipes.

How are they going to fit a 347?

should be fine. I have a FiTech that also has one O2 sensor and I plugged the other side.

I have Gas'n sidepipes too so if you had to switch I probably would too.

The Holley Sniper O2 fits perfectly into the bung already welded in the collector. There is one on each side. Pick one side, it doesn't matter. The bung plugs are already installed from F5.
