Hi -

I will be installing an Offenhauser 4 bbl intake manifold and factory Ford dual exhaust manifolds on my 300 six. Does anyone have recommendations for what gaskets to use including mounting hardware? The engine appears to be 1977 vintage. The engine is in my 1966 Ford F100.

Thank you in advance.

There are a lot of good detailed write ups if you use the search. But, I think most recommend the Mr. Gasket #260 and grade 8 studs. This is the route I went. You may also need to deal with a thickness difference in the EFI exhaust and intake manifold, some use half washers, I used a 6" belt sander to flatten the efi manifolds and gauge their thickness.
