Question about plate length

[JohnnyIC]

I just have a quick question about valve plate lengths, short plate vs long plate. I bought two NOS Brimar 12AX7(ECC83) valves, one is a short plate version and the other a long plate version. Can I use these together as a pair or would their sound characteristics be different?

Thanks
J.
