There are quite a few things you can do to help solve the problem, but what we've been doing on the circle track cars we work on is not use a gasket at all. We just use the ultra hi temp copper RTV sealant. This was kind of discovered by mistake because we needed a gasket on one of these cars in an emergency and didn't have one. We figured we would patch it up with RTV and just hopefully get through one race with it, and then fix it during the week. Well, the sealer worked so well, we just left it and it lasted almost a whole racing season, and in fact, was still holding up until we pulled the engine out for freshening. I would also suggest like Mike said, have the flanges checked for flatness. If you are having problems with the bolts constantly loosening up, you may want to also look into the Stage 8 brand fasteners with the retaining clips on them.

Re: Source for header gaskets that won't blow out?
Before you install that header again, take it to a machine shop and get it
machined so it is flat. The flange that bolts up to the side of the head can be warped to an amount that is greater than the gasket's ability to correct. When I bought my Borla header, the flange was badly warped and the gasket would never have filled the gaps. I put it on a large flatbed belt sander until all of the high points were ground off. I installed it without a gasket almost 4 years ago, and it still doesn't leak. "travis" <travist34removethis@hotmail.com> wrote in message news:iqfqrvgh5n0mptofhifb9a48hskjg9ct00@4ax.com... > ARGH!!!
