Default LS1 to LS6 Intake Swap

Can someone give me a rundown on exactly what is needed to do an LS1 to LS6 intake swap please. What I need to know is will I need to change or modify my valley cover and what about the coolant lines? I know its been posted before but I did a search and came up empty and I don't have a lot of time as the intake I want will likely be sold soon.
Also is an LS6 intake's part number 12573572?

Thanks,

Brett

Extra $500 ?? I only paid $500 for my FAST in the first place. Maybe you guys are getting ripped off. I had the option for 78mm LS6 for $459 or 78mm FAST $500
I chose the FAST Enough said.

I was told that I would make more power by taking advantage of my VaraRam ram air setup using the FAST vs the LS6. Please explain if I was misinformed.

You were misinformed. It's only a good upgrade if you can get the LSx 78 for the same price as an LS6. The gains are very small and you could spend the money in better places.

The FAST 78 is a good setup if you want to do a nice direct port system due to the designated spots for it, but if you can afford a direct port system, you should have enough cheese for the FAST 90.
