318 exhaust manifolds on a 360

I ran across this thread. So not shure if it is ok to bump it or not. If not please Mod delete my post.
So what did you end up doing?
I am lucky I have 2 sets of 340 ones. So ported my 1970 for my 70. And will use my 1973 ported 340 ones on my 73.
Is it worth saving the 2002 Van 360mag ones I have on my Van that is going to the crusher?
