4 manifolds are the same for up or down exhaust.
Outlets are changed on the ones that turn down. Depends if using a distillate, kerosene or gas manifold type on the outlet parts needed. Other than getting lucky and finding used or NOS parts, fabrication of outlet parts may be the only option. H manifolds less outlet pipes are the same.
For one just like a original I presume gasoline 450 manifold, used is all thats available. Good ones lots of times sell for about the same money as new aftermarket ones or sometimes higher.
