Hi Bill
The formula for determining the input impedance
for a triode operated in grounded grid is given in
the Bill
Orr handbooks.  In the 21st edition on page 7.18.
In the 23rd edition (newest one)on page 15-14.
There is also a list of operating parameters
(including drive impedance) for some of the more
popular triodes operated in GG on page 15-18 in
the 23rd edition.
Hope this helps.
Paul
