Coils don't match???

Looking to tap into the vast knowledge around here and ask if my bike is what it is. I have what I believe is a 1981 KZ1000 police bike (all paper work history indicates this is an Oregon State Trooper bike), however, all the listings for my bike have coils at 3.5 inch mounting spacing and mine has 4 inch.
Normally guys don't complain about being to long but I'm fearing one of my 1-4 coil might be acting up. It idles fine, runs good for a while then has a bogging down effect like it's missing on one cylinder or fuel starvation. I've rebuilt everything in the fuel system and am confident it's not that.
My question is, if I have to get new coils (no point in getting just one) what coils to get if all the listings for my bike don't fit? I have looked at these but am not too sure. www.z1enterprises.com/detail.aspx?ID=1711 but Z1 lists these for my bike. www.z1enterprises.com/detail.aspx?ID=2857
Thanks for any help.
BTW, I've replaced the wires with Z1 NGK splicers and the proper wires. Still waiting to complete a long test ride, damn work.

Cut off the electrical terminations, strip the insulation back about 3/16" and using a proper crimp tool, crimp on new ring terminals. Don't loose the supplied terminal screws as they are the correct length for a good tight connection. If they get misplaced, a 10-32 X 5/16" long screw will work, anything longer will bottom out before the screw gets tight.

If so you don't want 4 ohm coils, but 2.2 ohm - primary coil resistance for electronic ignition should be about 1.8 - 2.8 ohms.
Dyna's 2.2 ohm coils:

I'm at a loss because everthing electrical checks out. I'm starting to think it might be the old carb boots (manifolds) but would they run fine cold and just start acting up once the bike is warm?
I should add this problem has gradually gotten worse over the past month.
The loss of power, sputtering, bogging down and just crappy running at temp is getting to me.

Too tight valve clearances could cause these symptoms.

1. I purchased some "Glyptol" (Glyptal?) a high temperature insulation brush on varnish to prevent the iron laminations of the coils from rusting.
2. Check carefully the mounting hardware and spacers for the new coils for how close to the primary side wiring. More than a few riders have shorted out the wiring and blown a fuse, making for some head scratching as to why.
