They are both twin triodes exact pinout compatible. Both have 6.3V dual filaments.
They are both designed for use in cascode circuits.
Can't find to match the transconductances of the two.
The 6DJ8 is available used and tested for $6.50 and
The 6BZ7 is available new for $4.50.

Try the 6BZ7 cant hurt.
