Mine are MSD Street Fires like yours, so I just went out and measured them. Only did five wires due to attack of laziness.

nos 1 and 2: approx 1.9K (They are the longest, so this makes sense)
nos 5 and 7: approx 950 ohms
no 4: 1.45K

So, I'm gonna call mine good until I get motivated to do the remaining three. It's hot out there!

Will probably have to make new wires when I install headers, so will go with better MSD or Taylor wires then.

For what it's worth, I read where brand new carbon core wires have 10K ohms/ft resistance or more.
