5.2 Magnum exhaust manifolds on a Valiant?

I wanna try the stainless shorty headers on something with a little more room. Have any of you guys & gals tried Dakota stainless shory headers on a mild SB E or B body. I read a post about Jeep magnum headers and didn't know if they were the same design or different. This seems like a great choice for moderate performing 318s with good ground clearance....
