Looking to buy another speedo head on my 55 Belair. Any advice?

It might just be the cable. I'd take the center out and clean and lube it and see if it goes away.

I second CN's post.... most generally this is due to dried/hard/missing lubricant in the cable. Try lubing the cable with 'suspended graphite'... and see if it addresses the issue before you replace the speedo head...

If you need a new cable ATP sells a new one for a 72 Chevy 1/2 ton 2wd TH350 that fits perfect about $15, available at most parts stores.

Don't overlook the speedometer itself. Right where the cable goes in gets dry/gummy and seizes up and will trash a good cable. You can oil it the easy way from the outside, or take it all apart and do it right. Don't break the speedometer needle!
