Hi Po exhaust manifold washers ?

I have those repro manifolds from Shaker and painted them with VHT manifold Hi Temp paint and after 2 years still look great. There in a 74 Duster with a 318. Make sure you read directions and follow heat cycle posted on can. I stay away from headers at all costs, because I don't race I just go cruising and like the longevity of cast iron manifolds. I even have repro cast manifolds on my gen2 hemi and after 17 years still look great because I had them Jett coated before installation.
