I decided to go with headers on my car and have some w and z exhuast manifolds for sale. There is a crack on driver side manifold but all mounting holes are open and good threads where exhaust pipes bolt up. $150 shipped. PM me for pics if interested and I can email some pics. It's says the file was to large to load them in the thread

 

Is the crack on the center port inside or out side ?

 

The crack would be between the manifold and the block, not the visible side of the manifold. The place that put the motor together last year was supposed to weld the crack and mill them to true them up and when I took them off it looks like they missed the crack. Maybe it's just the way the weld looks, I can't honestly tell, but I feel good advertising them as cracked so people know what to expect
