Yeah, your experiencing nothing new. There has always been fitment issues with full length headers on Mustangs. I installed JBA midlength headers on my 351W to avoid any fitment issues. I might have sacrificed a few horsepower, but they fit great. I wish I knew what the best choice would be for your Cleveland. I do see some manufactures specify headers for rack and pinion steering. I know most people use either Hedman Elite series, something from Ford Performance Solutions, or JBA headers if they offer it. Good luck.
