I found a set of exhaust manifold/riser spacers that are drilled and tapped for an oxygen sensor. I would like to take the guess work out of tuning my carb and hook up an A/F ratio gauge. Does anybody have any experience with this? Do I need one sensor per manifold or can I run a sensor on just one side? If I do run two sensors, do I need two gauges or can I wire both sensors to one gauge? I am totally dumb in this department and need all the help I can get.

You can do it with just one sensor. You can switch sides just for peace of mind.

FAST has a unit that will read two A/F probes.

P.S. don't leave an unpowered probe in. If you have it installed, you should keep power to it whenever the engine is running.

has to be a heated sensor.

All you need is one sensor
I'll have to be heated
One guage . . . switch sides if you want to double check
