Header install?

I'm pretty sure I laid my TTI long tubes in the engine bay and sat the motor on top of them. I don't recall it being crazy difficult to do, but it was also over 10 years ago at this point. The thing with the Hemis is the exhaust ports almost point down instead of sideways, so it might be easier to install the bolts from the bottom than the top. I still have a factory K frame and torsion bars as well, though I did convert to manual steering (and already had manual brakes) when I did my swap.
