I just bought some black Holley LS valve covers for my 02 ZO6. I went to install the coils onto the covers and the spacing was off. The spacing on the covers is too wide for the coils. The part # for the valve covers was for my application. I did not even see another part # for the black covers at all. Are there differences in the coils from year to year? Did I just get the wrong covers? Any ideas?

They only work with LS3 72 mm bolt spacing coils.

Will the LS3 coils work on the LS6?

I see that they will work. Will the truck coils work as well? Are they 72mm. They have about 20 different part #'s to choose from....

The harness plugs are different from the LS1 to the truck coils ,If you get the plug end with the coils you can rewire the truck coils. That what I had to do .
