I just swapped my stock heads out for the livernois stage 1 ls2/ls6 heads.

Went buy LS1howto's journal (read the rocker arm torque spec's wrong torqued to 22 1/2 then 24ft lbs)

Anyway started it herd the rocker's clicking pretty hard but could hardly tell there was a cam In the car Idle sounded stock?

Plus my interior lights were kinda flickering with the cam surge's consistantly..

I have the Pcv mod dont know If I hooked that up wrong..

But It ran like crap Any Help would be major step forward.

Slowly brought up the Rev's the first time it shut of at 3100 rpms started it back up and was better but still ran like crap

 

What cam? Did you tune? more details please.

 

224/224 581/581 112 it already had the cam just added the heads..

 

You should still need a tune.

 

IT should still run fine on the old tune I only added heads..
