Headers - to be or not to be

My '70 SS looks really nice except for the rusty headers. Before installing the motor I used 700* stove heat paint and it burned off. The headers are in reasonable shape except for a pinhole leak in the 1/4" thick flange section on #2 cylinder. I am going to remove and weld in the pin hole, maybe. The next question is: do I weld / repair and send out for rust coating or buy a new set with rust coating already on them. Is it worth the cost of powder coating used headers. The Headers are Hookers. They fit perfect and I can reach everything as is. The new powder coated are $500.00+.
Thanks, Roland

Re: Headers - to be or not to be

Maybe just terminology, but powdercoat will not last on headers. I assume you really mean a thermal coating.

Re: Headers - to be or not to be

I would not personally send a used set out for coating. The Hedman Elites are $400.00- $500.00, fit good and are coated. Plus you can sell your old headers. Then you have a brand new set for the coat of coating your old headers.
On another note there is not a paint on this planet that I am are of that will not burn off on headers.

Re: Headers - to be or not to be

Try to find someone locally that coats headers, many powder coaters do. Bring it to them and ask their opinion as to the condition of the headers. If you buy new headers you will need to factor in the cost of modifying your current exhaust.

Buy the new ceramic coated headers. Mine are 6 years old and still look pretty new. The coating will dull over time but won't rust. The challenge with used headers is that you can't blast away the rust inside which in my opinion is just inviting problems down the road.

Re: Headers - to be or not to be

That really depends on what the amount of rust is. As someone who blasts and coats headers in a ceramic coating, I've seen it all. A majority of headers that I do are normally for vintage race vehicles or current drag vehicles that are very custom. Try visiting your local ceramic coating company for headers and ask about their process. The proper way would be to burn or bake any old contaminants, media blast them with a high grade media, and then coat from there. If the cost of the coating over weighs the cost of buying a new set then I'd suggest the new set.

If you can find/afford them, stainless is the only way to go long term.

Depending on the coating you may be able to use Mother's or Maguire's mag and aluminum polish to shine them back up.
