Parts wanted, 360 exhaust manifolds

Ok, I'm really torn between the Dougs D453 headers versus stock exhaust manifold. I'm leaning toward the manifold for ease of installation. I read the early 70's 360 were the best choice. This car is a driver, ac, power steering overdrive automatic.

Headers are on backorder right now but I haven't found any manifolds yet.

So, anyone know a good source for exhaust manifolds?


Thanks
