Bottom End.
Many people run that kind of hp with the stock short block, but usually, you'll need to spin it pretty damn high to get those numbers. Rod bolts are cheap insurance.
Regarding the head/cam combo, buy the best heads you can afford, then spec the cam accordingly. Numbers aren't everything anyway, it's all about the combo, combo, combo.
Tell us a bit about the car.

If rwhp #'s are what you are looking for that should be an easy mark to hit. If you are looking for track times then let me know. My car is running high 10's full weight with the stock shortblock.
Shift point of 6200? You're leaving serious potential on the table, as that cam was designed to rpm waaay up top.
Is the low shift rpm due to a sub-par intake setup (ls6)? You might even be maxing out the stock injectors with your current setup.

Year: 2000
Model: SS
Drivetrain: ls1/t56
Mileage: 113k
Price purchased for: $1800
Car was in a front end collision fixed, but not well, I plan to first take car of all the body work and get her painted.
I really would love to keep my stock heads and just change the valve train and achieve 450rwhp if possible.. That would be awesome and yes I would love top keep it at the stock shift points if possible.
As for the motor its completely stock same with the trans I plan on doing the clutch soon, I just ordered ebay headers. I need to get a lid, port and polish my stock TB... any other suggestions on a cam valve train setup would be awesome thanks!

Like the others said, I caution you on letting the "numbers" get in the way of the true goal. The combo and track times are what matter much more than dyno numbers.
As for the numbers, can the stock bottom end withstand 450 rwhp -- absolutely (depending on how you get there). I'm sitting at 600 on spray and that's easily flirting along the edge of what it should hold reliably. 450 - 500 shouldn't run into bottom end shortfalls as long as you're getting there the right way.
As for your setup, if you're sitting at 420 rwhp with that cam on stock heads, 450 is easily within range. Slap a nice set of heads on there (TFS or AFR would be a couple good high-end choices; personally I liked the appeal of the budget head options too) coupled with a FAST intake and you should be getting very close. If you go that route, be sure to spring for all of the supporting valvetrain upgrades and the bottom end shouldn't give you much trouble.

ok I got to hear your reasoning on this. ...by the way my stock bottom NA LS1 hits 450rwhp right at 6000 rpm on the dyno. ...and I have a A4
saltwaterreefguy I hope you got the answer you were looking for. Sorry the thread ended up going high and to the right, usually what happens when you start throwing numbers out there!
Okay, I've changed plans... I'm going to go smaller. I plan on doing ls6 intake, lt's, and supporting mods my question is below...
224/224 .581/.581 112 lsa
....is my stock fuel system going to be good or do i need to upgrade... Thanks.
