What paint did you use for your steering box?

I don't think you would have any troubles with using just regular old spray paint......but if you want to play it safe you could use some engine paint but I dont thing header paint is necessary.

if you can have hoses and plastic spark plug wire clips and things of that nature in close proximity to headers without melting that I do not see any problem with paint being on a your steer box thats a few inchs away
