[time-nuts] EFC divider resistors

I put a divider network in the EFC line of my GPSDO to restrict the OCXO range to 2Hz. Now I'm seeing heat-related drift that wasn't apparent before. I put a 20K resistor from the same strip on my 3456A, and the warmth of holding it between fingers moves it by about 50 ohms. What type of resistors should I put in there? Or am I chasing a problem that doesn't exist? Totally out of my league here.
