Mr Gasket #260. Soak them in water before installation.

F. Flyer: Thanks. For how long do I soak them, and wil the bolts need to be retorqued as they dry out? Thanks, Inline.

They have a tendency to get brittle over time if left on a shelf. I hoard them so mine may be very old when I am ready to use one. Soak it for an hour or or wrap it in a wet towel.
Its always a good idea to recheck torques after running an engine for the first time.

TFTF ------ Is the Mr Gasket 260 still the best for my 300 street motor with Offy Dual Port Intake and Ford HD Exhaust manifold? Does Fel Pro make a good gasket for this combo?

I never ran a HD exhaust manifold so I can't answer that one intelligently.

Fel Pro is a 2 piece gasket - it uses a factory style intake gasket over a exhaust manifold type gasket. Just take care when installing. I used some w/strip glue or dry tack glue in between the 2 gaskets to make sure they would not shift while installing. It seems to help. They are good gaskets.

Another tip - do not tighten the 3 bolts that hold the 2 manifolds together until you tighten the manifolds to the head.

Thats not what he put in the post. He said " Is the Mr Gasket 260 still the best for my 300 street motor with Offy Dual Port Intake and Ford HD Exhaust manifold? Does Fel Pro make a good gasket for this combo? " That is the question I was answering.

My choice is the Remflex # 3005. It's a good gasket but it's not cheap.
