need a little help im looking for a head and cam package by the way i have 2000 sierra scsb with a 6.0 lq9 vortech supercharger running 8psi long tubes e fans 4l80 3.90 gears and wheatley tuned iwas looking at the tsp package i dont know to go with a stage 2.5 ls6 head or the 2.5 l92 and on the cam im lost i have the stock converter but i whant to go with a 2600 any help will be appriciated

 

I wouldn't really recommend more compression with FI, do a smaller pulley and a can and you should be good. I'd you really want heads but keeping compression hop minimal do some ported 241s. They'll breathe a little better with small compression gain

 

Good advice. The LQ9 is already 10:1 so unless you're going E85, you are pretty close to max on compression. Unless you are going for an all out system (ie:forged bottem end), high $$$ heads are a pretty low bang for the buck. There are too many examples of 700+ RWHP LS1's on LS1Tech with stock 317's. Spend your cash on a blower cam, a smaller pulley and Meth (if you don't already have a kit). You can reach your stock short block HP max on stick heads without breaking the bank.

grate thanks i will keep my heads, i have the smallest pulley vortech make for my supercharger and i only make 8psi, any good blower cam will a 90mm tb fit my stock intake, where can i get a good meth kit

 

look around.

WTB adds, ebay, CL, etc.
and making 8psi on the smallest pulley? buy a better blower IMO

 

Use the search function, and do your research before anything.
First of all for the Cam I would recommend the GT2-3 or GT-7 many have used them with boost, and got great results. The 90MM T/B won't fit because you have a 78MM So unless you get a 90MM intake that won't work. The meth Kit you Can Google and find different brands and names dependeing on what your wanting to spend.
