anyone have any suggestions for a header for me that doesn't have clearance issues? i'm dropping a 454 in an 80 el camino.

I think the only two companies that make big block full length headers for a G-body is Hooker and Hedman, and they still have some clearance issues...especially if your planning on keeping the AC. Go to www.maliburacing.com "click" on the tech section, and then "click" on the BBC in your G-body Page for info.
