I got a set of SBC hooker super comp long tubes with a parts car that I bought. headers are solid, just rusty.
Is there a high temp paint that I can spray over the rust? Not sure I want to put the $ into finding and paying someone to sandblast and coat them, will probably just get new ones if I cant make these ones look decent with some kind of paint treatment.

Have them blasted, then get something here (http://www.eastwoodco.com/jump.jsp?itemID=394&itemType=CATEGORY&iMainCat=390&iSubCat=394)

buy some scotch-brite pads from fine to coarse or 60 grit to 180 grit.sand your headers down then apply grease release agent to thoroughly clean them.next get a large bottle of anti-seize and coat the entire header with it using an old t-shirt or lint free rag.now with a piece off wire hang your header and apply heat evenly over the entire header with a propane torch or heat gun.when the header starts to smoke from the heat source stop and let them cool completely down.repeat the heating cycle about 4 times then install them on your car.you now have a cheap version of alumna coated headers that the coating will not come off.

I'd like to see pics of the final product, sounds interesting.

I used a mouse electric sander and 200 grit pads to sand mine. I used VHT 1000 degree manifold paint. When I was done, I couldn't fit them in the oven, so I installed them, fired the car up for a minute and turned it off. I let it cool and kept repeating several times for slightly longer intervals. That was two years ago, and the paint still looks great.

take some 100 grit sandpaper and then get some dupli-color 1500 degree header paint, you can get it at autozone and places like that. and ou will be amazed what it will do. it will last a whole lot longer than the factory coating.

if they are in good shape and you don't want to mess with them i'll buy them

The manifold paint I used the other day, said it has ceramic in it. They look real good so for, but only have about 50 miles on them. I just hand sanded, washed, dried, sprayed and then hung them in front of my Ben Franklin wood stove. Not sure if it made a difference, but seemed like a good idea at the time.

my dad gave me a set of headers that have some lillt rust on the outside ,so i fugre ill scotch bright and paint them but...the inside walls are really rusty and have a rusty powdery film that falls out when turned upside down,is there anything i could do about that

sanding headers isnt really any fun, I'd get a drill with a wire wheel on it for faster sanding if you dont mind a few very fine scratches on the surface

I would drive them the way they are. Around my part of the country, we call those headers "oxide coated", and they will match everybody's headers if they are a year or more old.
I have had painted headers, aluminum coated headers, and ceramic coated headers. The aluminum ones last the longest. Even the ceramic coated ones rust here very badly the first Winter, so I don't even try to keep them looking nice anymore.
Just tell everyone you have the latest technology, "Oxidecoat headers" http://www.nastyz28.com/ubb/smile.gif

lol http://www.nastyz28.com/ubb/cool.gif i like the idea of oxidecoated headers but,the inside of them are a little rusty and have an exaust coating over them, is there anything could do about that?
