Best headers for BBC??

[77BBGMC]

I'm a little partial to stainless, I like the way it looks and holds up but you have to pay for it. I had to do a little hand forming on mine and I'm not sure how the coating would've held up? I do plan on taking mine off and getting them ceramic coated someday, should be good to go since they will bolt right on now.

This doesn't answer your question but my observation has been that certain series of stainless are more resistance to corrosion than others. We supply some Mfg parts that are domestic 304SS, corrosion isn't really an issue in fresh water but salt water applications create some challenges. After lab testing, the most cost effective solution was to electropolish the parts after completed and polished. I haven't done any research to see what series of stainless header manufactures use. Like I mentioned earlier, I ended up going with painted headers due to $$$.
