Post long-tube headers - heated O2 sensor?

Okay, before you go saying "this ain't advanced" it IS advanced for a second-gen car, and I figure there is alot more experience with O2 sensors here than in the Classic Tech forum...

Anyways, I'm putting an A/F ratio gauge on my '77 to help tune the carb. Of course, the car will have the standard long-tube cheapo headers, and I've heard that the exhaust cools enough before it reaches the collectors on these that an O2 sensor won't reach the proper temperature to be accurate.
Now, keep in mind, the reading from the sensor doesn't have to be spot-on, just pretty close - the gauge just has about 10 bars from 'rich' to 'lean', and the carb isn't as accurate as EFI.
So, will a standard O2 sensor suffice, or does it need to be a heated?

Also, I called the NAPA guy to get a price for a heated O2 sensor, and he insisted that he needed a specific part number "because I'm sure they're all different". I'm sure there might be some differences, but isn't the signal from one O2 the same as from another, and the gauge won't know the difference?

BluEyes,
I am not sure why you think this isnt a advanced question for other years but is advanced for a 2nd gen. When you break it down this really isnt an advanced question.

All I ask of people is to post their question in the PROPER forum first and try there before making a post in Adv Tech. And I dont mean post it there and if you get no responses in 2 hours its ok to post here

We have multiple forums for a reason, dont sell them short there are knowledgable people in all of them.
