anyone out there put a older set of heads on a third gen camaro..like say off of a early 70's 350..I came to find out the manifold bolts were different on them as compared to the 305 heads that would come on the car..anyway was lookin into what kind of headers i would need..all the bolts are the same except for the passenger side back bolt the 305 manifolds have the bolt back too far but all the ports line up and the driver side bolt holes and ports all work..

 

You might want to post this in the engine/tech section.

Pics would help as well.
