bolt on bolt action sounds a little umm


there are studs that come out of the motor the header slids over and nuts tighten it down....

Does your car currently have an exhaust manifold installed? If so, you can probably reuse the hardware for installing the header, provided you don't break any of it. If your header came with a new gasket, you'll want to use that instead of reusing the old one.

IIRC the stock setup has studs w/ nuts on them to hold down the manifold.


edit: doh, 81gsl12a beat me to it.

K let me know. First thing you need to do tomorrow is go buy a can of P B Blaster, no WD-40 bs either. You'll thank me later or you will be bringing the car up for sure.

Before you start taking the old exhaust off, put the header and pre-silencer together, slide it under the car and see if the length is correct for a direct bolt in. Not all of them are.

Even if it doesn't fit and you need to bring it up, PB all the nuts and bolts anyway, that will save a bit of time.

Soak everything in the PB for as long as you can before you get started. Also, clean off any exposed threads on the end of the studs with a wire brush before you try to take the nuts off.

If you really have to torque on any of them to get them loose, rather than risk breaking one and having to drill it out take the time to put the torch to them. Heat the nut up really good, then place a wet cloth against the end of the stud. This will cause the stud to shrink slightly while the nut is still hot and expanded. Works for me in most situations.

Make sure that you use a good sealant on the block-off plates too.

Beeswax works good for drawing the heat out of the stud too.

Correct. If you have access to an acetylene torch, heat the nut red hot, quench the stud, then immediately start removal. I have never had to go to that extreme yet though.

Usually the combination of the PB and heat will break the rust bond.

make sure the nuts are the right thread pitch for your studs in the block. The hardware that was supplied to me by racing beat had the wrong thread pitch on the nuts and stripped the studs, so i had to get new studs and nuts, not that big a deal b/c they are pretty generic and readily available at any napa, but still just make sure.
