66 valiant with 360 help needed.

well that sucks. im glad i asked before i bought them. is it possible to grind on the manifold and the head to make it fit? looks like im going to have to pony up for a set of headers.

what do you guys recommend for headers. fit, finish and performance being most important. cost is what it is. if i have to shell out 800 bucks for a set of pipes that will last forever then thats worth it to me.
