Spit 1500 headers

[Martin_A._Secrest@NEB.VOA.GOV]

My stock Spit 1500 exhaust manifold is warped and hairline fractured.

So far the fracture is holding, but I realize that Murphyºs Third Law of 
Mechanics
proclaims that a part that might fail will indeed do so, but only at the worst 
possible
moment (that is, when you are far away from home and a replacement part).

So I want to put in a header.  I know the Monzas are a lousy fit.  Are Kirk 
headers
any better?  Or is there a third alternative?
