what coils should I use

Ive got a 1982 kz1000LTD. Ive read through the forum and I thing I need 3ohm coils but Im not sure. Also any recomendation on what brand of coils have worked the best for you would be great. Thank you for any help!

Same bike but 1 year older than yours. Specs called for 1.8-2.8 ohm coil so I used the 2.2 ohm gray Dyna coils. I've had them for several years now and they work great. They go for $120 and up for the pair.
