I have a pretty stock 07 4.6L just basic bolt ons and a tune. I’ll be purchasing the Roush Stage 2 Supercharger Kit link provided at the bottom. I’ll also be installing a cam as well and fuel pump. Car mainly is just sitting and getting parts thrown at it so next will be suspension, transmission and driveline etc. This is just first thing I want to get done. I was thinking about buying new heads to put on when I install the supercharger. Basically what all internals should I upgrade when installing this? Any other optional or recommended parts that would help performance or longevity of engine and supercharger? Thank you in advance.

You could run that supercharger with the stock engine internals but it's better to upgrade to forged rods/pistons, a HV oil pump with billet gears, and a higher capacity oil pan for long term reliability.
