I have an exhaust leak at the collector gasket on my Ford 302 engine. I made up my own "H-Pipe" for the exhaust and I think I am a hair off on having it line up with the driver side header. I can bolt up the collector fine but I have a small leak at the top side of the collector when I use stock style collector gaskets. I looked in a few local auto parts stores today but I could not find any of the dead soft aluminum gaskets. I found a set of thick Spectre gaskets (some sort of graphite-like material) that I guess I will install. My question is this, can I double up on these gaskets on the left side to prevent a possible leak. Will doubling up lead to a leak between the two gaskets where they press against each other?

Thanks for your ideas.

I have heard of people doubling up on the copper type collector gaskets with good results. I have never tried it myself but seems like your best bet.

Problem solved!! I doubled up on the gasket and the leak is gone.

Make sure to re-tighten them a few times after it goes through some heat cycles. Also, keep in mind with the double gasket it will be more prone to blowing out so you'll want to check them often.
