I did a search in Camaros.net for header info and found mostly questions on what headers will fit. I found nothing on what gaskets to use with headers. One or more of my header pipes are leaking resulting in a loud ticking noise on one side of the block. I am suspected the #7 cylinder (left rear) since that is where the noise appears most prominent and I can see a crack at the top of the gasket above the port. I'm not sure of the make of the headers. Are there choices on header gaskets? If so what should I look for? I'm looking for tips on how to best seat the headers to keep them from leaking.
Thanks,
Mark

Mark -

In my experience the biggest problem with header leaks is loose bolts. Some or all of the bolts ALWAYS loosen and then exhaust leaks out and cooks the gasket. Try a new set of gaskets and get some header bolt locks. Check them a couple of times after you run the car with the new gaskets and re-tighten the bolts as the gaskets settle. BTW - the Checker Auto on Quincy in Aurora carries high performance parts incl. header gaskets if you don't know of anything else local.

I second the motion for header locks. RacerX has them as well. I think he was tightening header bolts every 2 weeks until he got the locking heads. Now they never move, you can get them from Summit.

I suggest using the Mr. Gasket "Ultra Seal" gaskets. I have used these many times with great success. I have also heard of soaking them in water before installation, to form a better seal, although I've never done it. Also, a common problem is over tightening the bolts, which warps the mateing flange, and creating a leak that burns out the gasket. Just my 2 cents worth.

Thanks for the replies. Tonight I removed the six header bolts. As I pulled the flange away from the block the gasket fell apart on the end. I'll be out tomorrow morning looking for a new set of gaskets. This header is a little tight due to the power steering box.

Spend the money for top quality gaskets such as Fel-Pro. I did once and have been doing so ever since. You may also want to have your flanges surfaced to ensure that they're flat.

Went through a bunch of gaskets over the years. Tried everything. The Mr. Gasket Ultra Seal did the trick. Kind of amazed me that they work so well.

Factory type metal gaskets work really good, too. The white paper things sold for headers burn up after a season, everytime

I ended up getting the Mr. Gasket Ultra Seal since it looked like it would last much longer then the paper version. I finally got it installed on Sunday. The difference is amazing since the loud ticking is gone and the engine now sounds normal.
