Personally, I’d just wrap the header.
cermic coating from algheny metal works
he did my manifolds and came out awsome!
rusted cast iron to wonderful smooth bling
do it right and do it once
I will probably wrap the header… maybe even a sheild around the charge pipe too.
I wish i would have taken the header to get coated, but i never had the initiative to actually go do it. Now, its such a PITA to remove that I probably wont do it… maybe rattle can it :eek3:
