I have seen some questions here about what headers fits on wich engine or wich intake manifold I can use on what engine.
So I have done a little thing that can be of help to see how the intake and exhaust ports are spaced on different engines and what headers/exhaust manifold or intake manofold can be used from wich engine type to do a convincing setup on your model.

Because it doesn't look good with evenly spaced headers on an engine with siamesed center ports or the other way around :rolleyes:
