Just rebuilt my 302 and have a new set of Doug's Headers to go with it. How concerned should I be about warning Doug's states regarding breaking in engine and possible ceramic coating damage?

Re: Break-in

Luckily since you haven't stated that you installed your freshly rebuilt solid lifter 302. You can break it in on an engine dyno with a competent engine dyno operator varying RPM to keep fgrom wiping a lobe. Before ever firing the engine he would have pre-lashed your valves and set timing. That way you have a running engine to break in your headers properly.

I believe there is a warm up period then a cool then warm etc. for ceramic. when I had my headers cerakoted, I was told to let them set for 4 days before instillation

Re: Break-in

As Dave states have it run on a dyno if u can. I didnít and wished I would have. My Dougís headers are dull now. I could have broke in the engine with my old headers but I didnít want to pull it again. Now I have an oil leak from my fel pro one piece pan gasket that would have showed up on a dyno. Next time it comes out it will go on the dyno before it goes back in. There is a shop with a dyno in my town now. Money well spent.

Re: Break-in

Don't do the engine break-in with new ceramic coating. I ruined a set of freshly ceramic coated headers that way. Coating went dull for sure and deteriorated way sooner than it should have. Use an old set of headers or manifolds instead. That way you can properly bake-in the new ceramic headers when your new engine is all broken-in and the valves adjusted.

No, it's not stock.
No, it's not real.
No, it's not for sale.
It's just the way I like it.
