How to prep non coated headers.

Take them to a sandblaster & Pay ~$30 to remove rust, or the cheap Crappy paint they use from the factory.
Buy 2 cans of your preferred collor VHT Header paint
Hang/suspend headers for cleaning & painting.
Wipe off headers througoughly with rubbing alcohol or wax & grease remover.
Spray a few light coats over the headers.
Have a propane torch handy. Light torch- aim flame into the bottom collector tube- let run for a few mins- you will see steam/smoke coming up the top of the primary tubes.
Let cool down
Spray a few more light coats over the headers.
Heat with torch again
Repeat until you have the headers coated really good.

Heating with the torch will help the VHT cure. When you run the engine the first time, it won't burn off the paint now.

Nice i will keep this in mind when i get my new ones.

So I did the header coating by this process and I must say turned out real nice took about 3.0 hours total to do both headers

BEFORE PICS







AFTER PICS

I'm using manifolds instead of headers on my Caddy engine in my Elco. (not enough room for headers) I bought some black paint coating for those from Eastwood, and used the same procedure to cure the paint. Of course it take more heat for cast iron, to cure the paint........

right I here ya buddy

Oven baking them works too... well if your wife doesn't mind lol!

this is true Rago but you will not be able to use the oven for food again for the residuals of paint fumes getting into fumes and I would advise NOT using same oven you cook in LOL

Actually you can. My grandfather taught me that trick years ago & he used his oven again. Take a look inside your oven one of these days & you'll see that it's probably painted from the factory. It DOES need to air out, but the oven will still be usable afterwords. Besides, have you ever been hit with oven cleaner fumes? That stuff is 10x worse than any paint fumes I've ever smelled, not to mention the chemicals that are in it are known to cause cancer.

Powder-coating in your oven is a different story though. I believe that one might be a no no.

I have a self cleaning Oven so No worries
