welding MC 5 cylinder exhaust manifold?

[David Michael]

Hi Kurt

I am in MA, but not very near Fitchburg. Do you remember about what it cost
to have your em welded and surface ground? I found a  machine shop that does
a lot of engine restoration workd (Deusneburg straight 8s, etc)  in
Southboro who canl MIG and surface it,  but I suspect they are spendy.

Thanks!

Dave
