Heat Riser Position

[camaronut]

I'm ready to install a new exhaust on my car and wondering if there was ever a consensus on how the heat riser is installed?
Is the weight near the frame rail or under the exhaust manifold.?

I saw pics of so called original engine bays and saw them installed both ways - what's the deal folks??

Thanks!!!

This is how it is depicted in the 1969 Camaro Assembly Manual, Section C6 page 6.

That's what I was thinking - but wasn't too sure.
Thanks!!
