I have Sanderson headers and found their quality and customer service to be excellent. That said, sometimes they have a less than helpfull lady answering the phone, if you get past her to the tech guys they are extremely helpful. I have an odd ball combination that required me to modify the headers I got from them. They provided me with a box of scrap bends and pieces for $20 and once I was all done I shipped my headers back to be ceramic coated. They charged me just $115 for the Ceramic coating and had them back to me in less than a week. I was amazed. The headers fit great against the heads, so precise a gasket is not needed. Two years now and no leaks. I recommend them.
