Are all 496 manifolds and risers the dry system?

That is, wet joint to dry joint.

Yes. Dry joint between the manifold and riser.

Would going from a wet joint to a dry joint make it run hotter?

Just install them.

MIE 340 stroked into a 496. Simple bolt on and run.

How about from a 2004 496HO "closed cooling" to a 1996 454 7.4L?? I have read all thee above. Should bolt rtg up.

Thanks, John

Yes the outlet is a bit angled down but nothing the exhaust hose cant handle.

Did you notice any performance improvements? Even if no change, however, just going to the dry joint design and the weight savings would be worth it, IMO.
