    I have a set of unknown brand lake style headers on my coupe and the block off plate gaskets are starting to leak. I can't find anyone who sells them. The block off plate is 5 1/2 inches across, including the mounting flange. Holes are 4 on 3 1/2 x 4 7/8. The tube seems to be 4 inches or just over. Heat wrap makes it tough to tell.

    Have been to Speedway counter and they don't have them. A muffler guy claims on these flat style plates a bead of red silicon will do it, but there are gaskets in there now and I would like to keep using them.

    Any ideas on who might have made these? I suspect the were a kit. Any thoughts on the silicon idea or where I can find the gaskets or material to make my own?

    Take the gasket out and clean both surfaces then apply manifold sealant and reassemble. That's what I have been doing for the past 10 years and I have never had a leak.

    I don't believe that you can buy asbestos anything any more. And you won't if you value your health and life. :eek:

    Gasket material for exhaust gaskets yes, asbestos no.

    I wonder if it's just me, but I really dislike heat wrapped lakes headers.

  7. I used a sheet of copper I got from a roofer to make mine. They have been in use for 5 years I open the headders at the track a lot seals real good.
