I got a 99 Z28 a could nights ago in trade for my truck. The has 107,xxx miles on it pretty much all stock right now. Has a aftermarket lid and smooth below. T56 with new LS7 clutch kit. With the car I got TSP 2.5 5.3 heads, ms3 cam, ls6 intake, powrrbond 25% underdrive crankpulley, TSP 1 7/8 longtube headers, and TSP ORY. Im plannin on putting it all together within the next few weeks but I want to make sure I get all of the remaining needed parts before I start because I will have to dl it all in one day. I plan on getting LS7 lifters, LS2 trays, and arp 12 point headstuds. I know I need more but not sure exactly what else. Should I upgrade pushrods or rockers? What headgaskets should I run? Which timing chain setup? Im thinking tsp true dual setup or slp loudmouth. My end goal is 450-500rwhp. Please chime in if I forgot or over looked anything.

Maybe I posted this in the wrong section? I figured there would be a few good replies by now.

you should upgrade the valve springs too although i can't recommend any .. newb at the field, as long as you are going something different and bigger and better you'll need to do the same with what its working with.

e.g.
running a 2002 z06 ls6 cam : Camshaft Specs: Duration: 204/218 Lift: .550/.550 LSA: 117

stock ls1 valve springs wouldn't do the trick you'd need at least ls6 valve springs as they have a max lift of 0.570"

Try the internal engine section, you will get more hits there.
Hardened pushrods are a must, and at the very least you should rebuild your stock rockers (trunion upgrade). Many use the LS2 timing chain with good results.
