Yea, I think the reason more early Hemi "Readymade" sets aren't out there is due the many variables in early Hemi engine layouts, valve covers, with or without wire covers, cast or stamped, distributor types, etc. then there are the different boot and seal preferences. As far as which brand wire you choose when making up custom sets, there are many good ones, just a matter of preference. I'm currently doing a 392 build and will be exploring some other options as well, still not entirely sure which way the build will go, stone stock or a little crazy, blower, etc.
