Gotta read the fine print (see highlight):

Edelbrock flat out said these were very much designed towards the 6.1 & 4th gen hemis. Can you bolt a stock 3rd gen intake to it? Yeah, but that's gonna be your choke point. Here are the exhaust ports:
Very much a D port. They aren't very specific about the intake ports, but I'm willing to bet they're more like eagle/apache ports. Compare to early 5.7 exhaust ports:
I think they've designed the heads so it is POSSIBLE to bolt just about anything to it, but how well some of those possibilities may work is another story...
Now for the rest; you can't swap a 4th gen timing cover to a 3rd gen engine, they are not backwards compatible (front end of the VVT engines are significantly different) and the accessories are oriented completely different, in both car and truck configurations. To run a car or later truck intake you will need the altered
3rd gen timing cover (which has gotten pricey over the years:

The Victor intake would be an improvement over your stock intake, but running the OEM 6.1, eagle car 5.7 or active truck 5.7 or truck 6.4 intakes will be significantly cheaper and easier to install, though for the plastic intakes you'll need intake spacers to lift them enough to clear the temp sensor unless you switch to a car accessory drive or can clearance enough metal.
@chrisp2493 did the car accessory drive conversion in his truck and documented it pretty well. Might check that out, you have options but maybe not the options you thought you had.
They do, which is why they recommend 89 octane. Can you put 87 in? Manual says yes, HOWEVER; think about how much timing the PCM is gonna pull (and power lost) to ensure you can run **** gas without detonation.
