Default Header bolts and Gaskets

Who sells LS1 header bolts?

Also the Speed shop said I could reuse my stock exhaust gaskets with my custom made headers. Is this true?

Very probably. Stock manifold bolts work well on a number of the aftermarket headers. If you just have to have new ones, any dealer can fix you up. Although I have seen numerous posts here from guys that have successfully re-used their original gaskets, I bought new factory gaskets (steel) just to be on the safe side. HTH

You can get the LS1 header bolts and gaskets at the Chevy dealer. Should be a stock item, you can re-use the bolts and the gaskets.

I personally like the Camaro gaskets better for headers, they are round ports rather than oval and are better suited. I also went with the ARP header studs.

One thing to watch for is that some headers are thinner on the flange and many people have cranked on the bolts to tighten when if fact the bolt may be too long. Also watch for cross-threading, another common problem.

Good luck

Bolts are to long by at least a 1/4".

That happened to me. I reused the stock bolts (thinking they were better) instead of the bolts that came with the headers and they were just slightly too long. I found the exhaust leaks when I did my H/C work. Here's what my heads looked like when I took them off:

When I reinstalled them, I used the bolts the headers came with and have had no trouble since.

I personally haven't, nor have I seen any posts here from anyone who has. I've looked at their product and it's seems to be a very good idea, especially where vibration may be an issue; motorcycles for instance.
