You can probably get by with the 16 uH that's in there now if you add more
capacitance to the tune and load caps. You would have somewhat more Q than is
optimum but on 1.8 MHz losses will be minimal anyway. 

If you don't have a pi-network calculator spreadsheet, let me know off the
reflector and I will email you one. A few minutes with it will tell you all you
need to know. You do need to have Excel or the equivalent in order to run the
spreadsheet.

Or if you want, just send me the plate voltage and current you are aiming for
and I will do the calculations for you. It only takes a minute.
