wierd exhaust noise
just installed ls2 heads, long tube headers/ory, pac beehive valvesprings and i'm getting a weird noise from the exhaust. it's sort of an intermittent ticking noise. i don't know a ton about these engines so wondering if someone has had this. i'm wondering if it's a valve opening too early or something? i have NO idea and not sure where to start.
i've had O2 codes coming from all 4 (the 2 back ones are cause i don't have sims) ranging from high voltage/ low voltage/ slow to respond.
mods include the heads/exhaust/hpp3/portedpolished maf sensor...
thanks

it's a random noise and it's worse at idle. i had a mechanic quick listen to it and he said it might be the spark timing because i didn't get it tuned yet and i now have headers and heads.... i'll see what i can do about getting a vid

Have you thrown a MAF senor code as well? The only reason I ask is it might be a blown Eng. Sen. fuse which controls the O2's and the MAF. If thats blown is screws up everything. Happened to me.

Check if your spark plugs are loose. I used to have a ticking noise that would accelerate with the rpms and give me misfire codes.... I ended up having a loose spark plug. Sometimes it's just something simple causing serious symptoms.
