I assume you wired both in series. That should be enough inductance for 160m. Just for curiousity sake, DCR is a half an ohm per winding.

Well My 4-1000A Linear works fine on 160 with a FC30. Pi network input

The B&W FC series of chokes were all 3-30 mhz continuous coverage. The ferrite rods were only 3.5 inches long; too short to get the proper turns of wire on the rod to properly cover 160m. That's why they rated it 3-30 mhz instead of 1.8-30 mhz.
