Motorcraft Duraspark question...

I've got an AMC-labelled Duraspark box with the popular "TFI
upgrade" parts installed. Works great. Got the Ford TFI coil for
nearly nothing from a yard.
I installed a 1.6 ohm ballast resistor, a big ceramic job, bolted
to the inner fender (there is no resistance wire in my home-made
harness). The damned thing gets skin-peeling hot -- easy 500
degrees. I mean, peel-your-skin-off hot like the barrel of a
soldering iron.
The coil seems fine, only a slight temperature rise. The
Duraspark box is the same temp as the fender.
Is this normal?
