I run TA headers on mine and ground clearence was a problem because they point down. When I rebuilt the engine this winter I had a friend of mine, that work with metal, bend them upwards. He made a setup were he could heat them slowly so no damage was done. I think he bend them around 2" and now they are great, sits perfect in the tunnels on the transmission cross member and no problems driving anymore. Let me know if you want a photo of how they are now.
