'78 KZ1000 A2A: Part Identification

Hello,

I was wondering if anyone on here could help identify cams for me. I purchased my new-to-me KZ 2 years ago and literally only had time to start tearing into it for maintenance, recently. I'm checking valve clearance and notice "Made In USA" stamped on the cams. So my curiosity is piqued and I notice "CWC EP14" stamped on the cams. I also see 108 stamped on them a well. I'm trying to figure out what I've got with this bike. The previous owner said it was bored to 1050 (he thinks!?!). That will take a bit more to verify, but I'm trying to understand how radical these cams are (or not) as I'm troubleshooting a low-end/idle stumble. Which leads me to the carbs...they look like the standard Mikuni variety, though I'm not 100% familiar with the model as I admittedly have only dealt with Keihin (flatslides and CV's). They need to be rebuilt, but I was pleasantly surprised with a Dyna S ignition and a Kerker 4-1 pipe (though the muffler had been mangled by the previous owner...GRRRRRR). I'll take any leads on new or very clean used (black) Kerker muffler if anyone has one?

Thanks, Ryan

picture?

CWC is the cam blank manufacture. EP14 is a Kawasaki KZ blank. The 108 is the lobe center.

Should be a grind number stamped on the ends of the cams.

Both intake and exhaust are showing: 13043 and 895.
