Reliability and engine longevity are of utmost importance to me as well... What kind of investment would i be looking at to make all this happen?
The springs and retainers will cost anywhere from $200-400. Most aftermarket rods come with larger/better rod bolts. Cost--$300-1000+
If you are building a daily driven LS/VTEC, and reliability and engine longevity are your top priorities, I would make sure to purchase the aftermarket springs/retainers, and strong rods. I have stock springs on my Type R, but I've been known to take the occasional dip to 10,000rpm.(I don't advise doing this regularly)
If you need any help finding this stuff let me know, I am a dealer for Rocket Motorsports.
