RE: Old stock Tungsol 6550s

No, that's a smooth grey plate (the second major version made by Tung-Sol) and they date from 1960 to 1963. The one pictured would've been made the final week of August, 1963 according to the date code.

Ideally, you'd have two of one or the other but these are closely matched (about 2.5% variance) so IMO would be worth a shot especially if you're getting them at a good price. Assuming you do get them, you will notice a difference in sound between them and the vintage GEC KT-88s you've been using.
