I just got my BBK polished ceramic headers. I just got done porting them out. There was alot of weld restricting flow so I just ground it done and it is about 100x better. My question is, I know with Stainless steel headers you have to clean the finger prints off before starting or they will remain there once they discolor, do I need to clean the ceramic coated headers as well? I have never heard of this being a problem on the ceramic headers but I want to be sure. Also if so, then what do I need to clean them with, will alcohol work?
