Is this a good combo?
 

I want to make some engine mods and I have some parts in mind. I'm hoping to get everything done over the winter so it will be ready to go next spring. I'm not after a specific horsepower number; it makes what it makes. I just want a good, healthy sounding motor that's not a nightmare to drive on the street and is reliable. Also, I should state that my car is a 2005 with 40K+ miles, so am I "too late" to make these upgrades (do I need a rebuild)? Would this make a good combo? I appreciate your thoughts on this.

Here is the parts list:
Trick Flow head/cam package p/n:TFS-K306-550-470
LG Super Pro 1 7/8" longtube headers with high-flow cats and 3" mid-pipe
LG GT4 exhaust
FAST LSXR 102mm intake for LS2
Nick Williams 102mm throttle body
Halltech CF102 Beeline Intake package (intake and Beehive shroud)
GM LS7 style MAF w/ pigtail to adapt to LS2 MAF
LG Super Cool radiator w/ engine oil cooler
160 degree thermostat
...and of course, a tune (Ed, what do you think?)

I'm locked into the exhaust...I purchase it a while back.
