Ok to heat and bend a pitman arm?

I've done some reading on it, and it sounds like you run into trouble with strength of the part being compromised when you quench the metal, letting it cool naturally is much better for the part. Also, I should mention, this car will see less than 500 miles on it in any given year, and no track time. Its an in town car mostly...4.30 gears...never goes over 70mph. I mostly want to get it back on the road...obviously its not a permanent solution.
