440 Six Pack Intake Manifold Gasket

[MoparHonda]

Can anyone suggest a manifold gasket for a 440 six pack with the factory intake manifold? I would rather not block off the heat riser crossover, I would prefer a faster warm up for driveability on the street.

I just bought mine at advance auto,never a problem.

Check out Summit too. They sell Cometic brand, which I've also had good luck with

I've always had good luck with the standard and block-off Felpro tin gaskets and with the paper sandwich adder gaskets.

Just get the felpro without the block off, readily available.

running full heat on a 6pak, or any other intake, with alcohol gas is a problem. generally i'll use the fel-pro gasket with blocked heat and drill a pair of 1/2" holes where the gasket blocks the heat. this does seem to regulate the heat some. don't use the papers unless the manifold has been milled to compensate for the extra thickness.

And the fact that you're in Florida, you don't really need the heat passage for warm up.

Thank you, all.

Agreed, do not really need the heat passage for warm up, but the choke stays on longer and it stays up on the fast idle longer than it should. Makes the car run kinda rich.

CORRECT!

Same for South Louisiana. I've always used the metal one piece valley pan+intake gasket heat passages fully blocked w some silicone around the head ports and on the ends and corners.
My intake is aluminum.
