    List what mods you currently have so we can better help you. Heads and cam you will need free flowing exhaust. You already have an LS6 intake so you should be good there. you will also need to make sure you springs in your new heads are compatible with the specs of your new cam. I am unfamiliar with that cam. also if you are an auto you might want to pick a TC and tranny cooler.

    I would also look at a racetronix fuel pump kit. Ported/polished tb wouldn't be a bad idea either. While you're at it I would start shopping for a 12 bolt rear.

    ah good point i havent even thought about the rear yet.. how much do our diffs generally hold? im bone stock so far.. low mileage m6. im still undecided about the cam i think i might go with the torquer v2. how beneficial is it to actually buy performance heads as opposed to building stock heads?

    You can pickup 50 RWHP with a set of Stage 1 LS6 Heads if you have the modds to pull it off with. 4.10s work better with 6 speeds. 3.73s work better with Automatics. LEAVE the MAF alone!! Just put down that screwdriver and forget about it.

    haha thanks. does anybody have the patriot stage 2 59cc ls6 head/cam kit? it says itll give me 11:1 cr. ive read that higher compression is useful in nitrous applications.. i know a bunch of you guys are daily driving with over 500 whp but ive also read that the connecting rod cap bolts are rated for around 500 hp. is that something i should worry about? im just trying to do all of my homework before i start ordering parts
