Tube substitute

Hello friends of diy audio abroad!
I am thinking about a new project building a tube amp... this one: DIY Single-Ended (SE) 6L6 / 5881 Tube Amplifier
Last year I bought two douzen 6SH7 and would like to know if the driver tube of the above project 6SJ7 interchangible is with my 6SH7???
The data sheets look very simular...
Anyone confirm in this matter?
