Silicone needed when installing new intake/manifold gaskets?
 

Picked up a new gasket kit from snyders (http://www.snydersantiqueauto.com/gasket-set-2006).

Wondering whether the exhaust/intake manifold gasket needs silicone or is it ready to go just the way it is?

No sealer needed

Forgot to ask also about the radiator/water inlet gasket.

install dry or maybe with a little spray sealer

I would not use that green gasket that's in that set, you will be replacing it in a short while, get the steel gasket or better still the copper gaskets.

I sprayed my copper ones with coppercoat - figured it cant hurt. Been spraying all gaskets with that stuff and seems to work well.

Confirming Brian T's comment.
I have seen the the green unclad manifold gaskets fail after a short amount of time.

I am also skeptical about how well any silicone would hold up with the extreme temperatures at the exhaust port.

I have had good luck with both the steel clad and copper clad gaskets. The copper clad are my preference.

Hope this helps

Do not use silicon anywhere near the fuel system. Fuel will dissolve/soften silicon and cause you some heartache.

I heartily agree with the comments about the green manifold gaskets, also pass on the one piece dimpled steel gasket, they don't fit right. Pay a little more and get the copper clad copy of the original. Ask me how I know!

Go easy when tightening the rad inlet. Many have snapped the ears right off. I learned here long ago many prefer a VERY light skin coat of "cone" instead of the gasket.
