Valley Pan Gasket
#1
Just pulled off my heads (351C 2V) today along with the intake manifold and noticed that there was a valley pan gasket installed for the intake manifold. Should I reinstall a new valley pan gasket or just new intake manifold gasket?

If you're going to reinstall the stock intake, I would recommend reinstalling the "turkey pan" since the stock intake is cast iron. With an after market intake, it's flip a coin. Some reinstall the turkey pan, while others pitch it.

My 2 cents,

Use the "turkey pan", it is what the car came with.
Can't remember its function, something about keeping oil
off the block.

Me, too. I've got the 2750. I didn't use the turkey pan when I installed the aluminum intake, since it cools better than the stock cast iron. The pan keeps oil from splashing up on the intake during high revs, so the intake stays cooler. At least that's how I understand it.

There's been much more discussed here if you search for "valley pan" on this website.

This was discussed last week.

The conclusion was to use it even with the aftermarket aluminum intakes. The purpose is to keep the hot engine oil off the intake which on a Cleveland in not liquid cooled. It will even help the aftermarket intakes stay cool and in summer can be the difference between running and vapor lock.

At least that is what I learned and plan to use it with my new Elderbrock Performer.

IF you're using an aftermarket aluminum intake manifold AND blocking off the exhaust crossover passage, then a valley pan gasket is not necessary (because there isn't any additional source of heat). If you think that you'll reduce the temperature of the intake manifold, by using a valley pan, your wrong. A valley pan is not an insulator that completely seals off the bottom of the manifold from engine heat, it's only an oil barrier for the exhaust crossover passage. <~~~ that says it all

Where is the exhaust crossover passage located?

But of course, that's what this forum is for! Smile
