Hi all -
I'm working on a 302 at the moment that has had steel adapter plates fitted to the heads for the fitment of headers on a wider bolt pattern than standard.
One problem it creates though is that std 302 exhaust gaskets will no longer fit between the plates and the headers, as the bolt holes are all wrong, plus, the heads have been ported and standard gaskets are marginal at best..
SO - does anyone know of a reliable source of suitable gasket material so that I can cut my own bespoke items? - preferably in UK but not essential.
I am also considering cutting them from copper plate. I did this many moons ago for a highly tuned pinto engine that we could not get a reliable seal on. They sealed well and each time the manifold was removed, we just cleaned then heated the gaskets with a smokey torch to soften them, then back on they went.
Question is, has anyone else tried this? - any pitfalls you can think of? and if I do do it again, what thickness plate would you recommend? I was thinking of about 2mm but can get it in:
1.36 / 1.55 / 1.67 / 2.07 / 2.26
