hi I need to replace the gaskets on my pacesetter headers and would like to switch to allen head bolts . but cant figure out what to order. this is for 94 3.4l thanks

 

Pull a bolt, find out the thread and length. Go to MSC.com and buy Stainless Socket Head Cap Screws. You want to skip the import versions and get the US made type. If you have a real hardware store they may carry them but there is a risk you will get imported crap. The imported stuff will work short term but the long term life is questionable

TIP: if you are having trouble with keeping the screw there are some kits out there but I am not sure if they work with the 3.4. If there is not kits or the kits cost too much buy your Cap screws a 1/4" longer and stack up a 1/4" thick worth of washers under the bolt heads. The longer screw handles the expanding and contracting better then a shorter one. Also red loc tight helps. I installed my headers 5 years and 100,000 miles ago and no leaks and I have never touched a bolt since.

 

thanks for the info . lock tight definitely will be used

 

dont use lock tight on header/exhaust bolts. they sieze in bad enough over time. better to check them a few times for tightness. what kind of header gaskets you using? percy's work dang good, reusable

 

just going with the pacesetter gaskets

 

I went with Stage 8 locking header bolts on my SS. I did not want to have to touch them after install.



Multi-layer steel gaskets seems to be the best choice.

 

pacsetter gaskets are horrible, what motor are these for? 3.8, if so the victor gaskets that autozone sells ($20) are great and look just like the oem ones.

an I used grade 8 bolts with lock washers form tractor supply, going on 3 years now, no issues.

 

well the pace setter gaskets that were supposed to be for my car are to long getting gaskets from auto zone hopefully they fit better
