I use to cringe every time I scrape the headers when I hit a bump or bottom out. I got rid of air shocks replace it with gas shocks and heavy duty springs both front and back. It raised the chevelle up, but the chevelle had a bad wheel hop. By adding Comp. Engineering Traction Bars it got rid of the wheel hop.I always ran Hedman headers that tucked up in pretty well. With the rear of our Chevelle sitting low, there was zero wheel hop and the header clearance wasn't a problem either. Can't say the same for Hooker headers.
Having the rear of the car up high is what is causing the upper and lower control arms to be so far out of their natural alignment that you are getting wheel hop. No hop bars or ladder bars may help eliminate the wheel hop, but they don't cure the problem. They are just a band aid that covers it up. No matter what you might think, GM engineers weren't idiots. You may improve some things on their cars, but often you will not......and i'm trying to keep that rear end up a little higher just cuz i like that look
