So I got my engine back from the machine shop today and it looks great. I still have a lot of assembly work to do. I am going to stick with the stock exhaust manifolds instead of headers. I have sandblasted the manifolds and they are ready for finishing. Should I paint them with high temp exhaust paint or put a header wrap on them or finish them with something else? Ceramic or "Jet Hot" coating is too expensive for me right now. Anyone have any suggestions? My Cougar is a 69 XR7 convertible with a 351W (M-code) and a toploader 4 speed. Thanks.

I used the VHT high temp spray paint from Summit. I've put about 2K miles on the car since then & the manifolds still look good. I did follow the inst. to heat the manifols up throug three heat cycles prior to installing them, not sure it was necessary, but it was worth the effort to me.

how did you heat the manifolds prior to installing? From the factory these were raw metal weren't they?

I used a strong solvent to clean the manifolds, then after spraying I did the first two heat cycles in the kitchen oven (while Mama was out). The third cycle was 600deg. & I did that in the gas grill. The silver color changed to a dull bronze, but they haven't discolored or rusted, so I'm happy.

Thanks all for the great info. I think I will try the silver coating from Eastwood. I'll let you know in a few weeks how it turns out.

por 15 high temp cast iron---sandblast first then a thin coat with a foam brush---let them dry a couple days--you can final cure on the engine but i take them to the powdercoater and let them hang in the oven for a couple hours--cheap and easy
