C6 ls2 build help
So I've been doing a lot of research and seeing mixed reviews on pretty much everything but I'm gonna ask and see how everyone feels. So I have an 07 z51 6 speed. I want to supercharge but I wanna start the build doing all the supporting mods before I put the blower on. Cam, heads, clutch and, etc... What should I really be looking to do to try and get around 600 rwhp. Should i bore the engine over what's going to be able to run that kind of power and be reliable. I don't drive the car all the time but when I do I'm normally playing around. Any and all input is appreciated.

No need for a cam or heads, total waste of money for your goals. Plenty have ran that on engines that have never had the valve covers off.
Blower, meth and headers is an easy 600.
Run the stock clutch until it stops holding. They hold up surprisingly well if you aren't drag racing.

My set up on LS2 minus the non power adders... A&A Si trim with 3.8" pully, ZR1 Camshaft, kook 1 7/8" catless headers, Flowmaster axle back... 625 RWHP. I upgraded the valve Springs of course, it ran fine of the boost a pump but I upgraded my fuel system after that anyways, the harmonic balancer is ATI but stock diameter. Max boost is about 10.8 lbs. Had to upgrade the clutch eventually, went with McLeod RXT and happy with it. Been making this power for over two years now on the stock block. The harmonic balancer and timing sprocket are the only things to give out.
So it's really just 3 things; S/C, mild cam, and full exhaust. You can add meth for safety or more power if you want but I don't find it necessary for me just yet.

What's the best supercharger? I was thinking of going with the magnacharger? So if the heads are fine should I send them out to get machined? How well will the stock pistons hold up? Thank you for your replies.

The magna charger "heartbeat" supercharger is only for LS3's. You could swap on some LS3 heads if you wanted to go that route. That is what I'd do if I went magna charger. I think you could use GM L92 heads, which are relatively cheap.
All of the centri kits will get you there. A&A and ECS are popular around here. Pro charger makes theirs too.

1. East Coast Supercharger kit
2. A&A Supercharger kit
3. Procharger kit
4. Magnacharger kit
I've owner an A&A kit and Procharger kit but I would purchase the ECS kit because their bracket system is a superior design in my opinion.

Hey, sorry for the late reply but wanted to give you the info incase it's still helpful. My cam sprocket didn't go, the bolts just came loose. A common problem on these engines with or without the S/C. Since we had to go in and tighten the bolts back up, I decided to throw the ZR1 cam in at the same time, used ARP bolts for the sprocket, and called it good. Same thing with the harmonic balancer, they give out on stock engines quite frequently. Upgraded to the ATI with an ARP bolt and never looked back. Since you have to pin the crankshaft anyways when installing the S/C, I would just go ahead and put an upgraded balancer on there while your at it so you don't have to drop the steering rack again. I would have had I known.
