    Heat!

    Getting close to firing up my Chevy 350 for first time.....
    It's fitted with DAX headers and side pipes which are a very close fit to almost everything - they are going to get very hot and so I'm wondering how to prevent melting/fire etc.....I've seen tape for wrapping the headers, but I dread to think how hot they'd get inside? Otherwise, it's stick on patches?

    Wotcha Fink?

    Hi. I have the same engine and ended up getting my headers camcoated. Made a big difference to heat in engine bay. Also put some heat proof boots on the plug ends.
    Cheers

    exhaust wrap or camcoating - only have experience with wrap and it makes a huge difference to underbonnet temps etc.

    Just bear in mind when you wrap the headers the heat will transfer somewhere which will be to the unwrapped side pipes . Owner beware on exit if you do not have heat shields fitted. You will also get more blueing of the side-pipes.

    Can someone tell me if it’s ok to wrap mild steel headers or is there a risk of cracking due to heat build up?

    Our mild steel headers have been wrapped for at least 10 years now (length of time we've had her) so probably considerably longer (built 2000). I re-wrapped them May last year as old stuff had disintegrated. Headers are fine, no signs of rusting or rotting etc.

    I have ceramic coated headers and sidepipes with Acustafil.
    The engine bay is cooler and the sidepipes surprisingly run cooler too. Not what I expected to happen.
    Used these guys for the headers https://www.performance1coatings.com/
    Informative, prompt service and excellent quality.
