I thought there was some 'issue' with the warranty on a truck anyway. As
long as you get the things hot, there should be no problem with moisture.
Past discussions with wrapping headers has actually been in holding too
much heat in, causing the headers to overheat and crack or melt. This is
especially a problem with stainless headers. Probably the best thing to
do is find a couple of sheets of stainless or aluminum and cut some
'covers' for the headers, and wire them to the headers or have flanges
that use the valve cover bolts to hold them on the truck to protect the
top end from the heat. Haven't tried this, but may, as I have a sheet of
stainless I can cut some pieces from.
