What is the exact torque the header bolts need to be torqued down to?
Do any of you guys recommend Stage 8 locking header bolts ( www.stage8.com ) or equivalent?
What about the header gaskets? Do the Dynatechs come with them, reuse the O.E. gaskets ,or buy another quality header gasket?
Sorry for all the Q's, but I just want to be prepared a head of time.

Not certian on the torque spec. Think its like 15lb. Whatever it is jut be sure and hit them again after a couple heat cycles. The headers should come with gasket (oem steel) and bolts. I used the bolts that came with them and they work fine. Put some anit-seize on them. I also reused the gaskets and bolts on a recent engine swap they have sealed up fine.

 

Those Stage8's will have you really pissed off really quick. Youll be throwing the locks across your garage! Breslin makes about the best locking header bolts availible. But they are not cheap. I opted for some stainless 12-point bolts. Stockers look like *** and tend to break.

 

The service manual specifies threadlocker (IMPORTANT-not on the first 3 threads), and torque in a two step sequence: 11ftlb then 18ftlb, starting with the two center bolts and then alternating side to side to the outside most bolts.

I have used the supplied gaskets and OE gaskets with the headers - they both work fine. I also reused the factory bolts, torqued to spec (without threadlocker, btw) and have never had a problem with leaks.

 

hey Jim, who's installing them for you??? or are you doing it yourself??

 

I would like to do them myself, but..... work seems to always have me 7 days a week!!!!!!!!!
Why do you ask?

Jim

 

Im trying to look for somebody to do mine whenever they arrive, I work quite a bit too, but whenever Im off Im just lazy, plus if I've never messed with something I dont want to try it myself cause I always mess up something... Im still on the look out to see if I find someone...

 

Maybe we can try and set an evenning aside and try it together.
I will definately be using a 1/4" torque wrench to set the torque where it needs to be. 11ft lbs the first time, then 18 ft lbs finally from the middle to the outsides.
I will be also buying Breslin's locking header bolts from Summit. They seem like they would work and save headaches later. May not be cheap, but i think they will be well worth it.

I just got pacesetters.... I couldnt bring myself to drop almost 1300 for headers and Y. even with cats... I am not sure if the dynas will make enough power over the pace's to bridge the cost gap... JMO though...

 

yeah, but we will pay as soon as we get caught without the cats . dynatech has a badass setup! hey jim, any word on the caltracs
