[Z06] Installing LG headers soon!!
I have the same headers, waiting for my lazy *** to install. I already have a 224/228 XE-R\XE Comp Cam installed. Just need to get motivated and do the headers.
FYI: I am using the PAC 1518 Nitrided Beehive valve springs. 30K on them with no problems. I will use the same when replacing. Below are the specs, I wanted a single spring, ovate, beehive and the .650 lift spec is substantially over my .588 lift.
Premium Nitrided Beehive LS1 Spring
OD: 1.290"
130 lbs @ 1.800"
337 lbs @ 1.150"
Lift: 0.650"
Keep us informed of your progress...

btw: I ordered the proform valve tool from competition speed (cpspeed.com) like two weeks ago. I still haven't got it. I've contacted them, but to no avail. That is all I am waiting on before I can finish the build.
What PSI should I fill the cylinder with? LS1howto.com says "60-80 psi." That seems like a big grey area……should I do 60 pounds, 70 pounds?
Thanks very much!

I normally just run about 30 psi... as far as releasing the pressure... I just un-connect the line from my compressor... a little noisy, no big deal.
BTW, once you have a cylinder pressurized and the spring compressed don't by surprised if the locks and retainer are stuck in position. I took a shop towel, laid it across the top of the spring\valve and popped it with a rub mallet. It is VERY helpful to have a pen-magnet handy.... to grab the locks... the whole process takes a little finesse but after you do 2 or 3 valves you will have the hang of it...
Honestly, I would not worry about too high a pressure... you do not pressurize the cylinder for that long... takes me an hour and half to change all mine....

I did the valve springs yesterday, and the headers and xpipe today. Overall, it was pretty easy. I didn't have any problems to speak of.
I still need to figure out the o2 sensor thing. I think I just need to extend the front ones. The port in the LG's is further back from the plug than when the stock manifolds were in so the wires will not reach.
I just have to do an oil change and retorque the header bolts and I'll be good to roll. Im also tinting the tails as we speak, so I wont let the thread die just yet haha
Thanks for all the help guys. I really appreciate it.
For your eyes only:
Old springs with rockers and pedestal off:

This tool was prime. I would highly recommend it (Proform LS tool). Very easy to use:

New PSI springs are in. Did new seals and locks too:

Headers are in:

New plugs, wires, heat socks. Intake, TB, coil packs, etc….are all back together.


Hope the vids work (sorry for some of the talking in em…):

[/IMG]As you can see though……my lights are NOT fixed. I have no idea whats going on. Is it a security thing? When I turn the key to the on/accessory position, they start going crazy….flashing and dimming….I can hear a clicking sound coming from the glove box/rear engine bay (relay maybe?) I don't see any blown fuses either and when I turn the headlights on, they stop flashing BUT the turn signals won't work (kinda flicker when on). They start flashing again once the headlights are off. Please help me get this sorted out!!!! My Z seems possessed!





The hyper flash occurs with the use of LED lights for brake or turn signal, are you using any?
