I am looking for a header gasket that has a port size of

1.8" Height
1.6" Width

I know the gaskets that came with my Jet hot LT's are this size but i blew one so i am looking for a better gasket with the same size port..

I have used SCE copper gaskets and they leaked alot on the bottom of the ports...enough to blacken the insulators on the plugs on all cylinders and both sides..

please give me some options for big d ports that won't blow out. This will be the third time doing gaskets and i'm sick of it...lol
