I had a VHF41 in my youth and it struggled on FM. You could try using the EF184 in place of the EF80s for more gain, and possibly fit an EF183 in place of the EF85. IF stability was always a bit marginal on these sets though, so you might need to adjust the bias - which is changed for FM operation.
