Cleveland Intake
I was wondering if anyone could help me out. I,m installing a Holley Street Dominator aluminum Intake. My question is on the Gaskets do I install the tin Valley with a aluminum intake I understand I shouldn't put any sealer on the intake side to allow it to move. But do I use the Tin Valley pan or just the fiber side rails and the rubber ends. I was also wondering the proper torque sequence and how many ft lbs to use on the alum intake I can find the specs for a cast intake but not this one. I would apprciate any Help Thanks in advance.

The purpose of the tin valley cover is to prevent oil from splashing on the hot exhaust crossover in then manifold and coking. The coked material is bad for the motor. Many people block the exhaust crossover and they no longer need the tin valley cover. The purpose of the exhaust crossover is to allow the carb to warm faster in cold weather.
Do not use the fiber gaskets together with the valley cover, use the fiber gaskets if you block off the crossover, or otherwise use the tin valley cover alone.
Do not use the rubber end gaskets. Just use Silcone sealer to fill the gap between the manifold ends and the block.

The factory intalled the paper gaskets under the valley pan between the valley pan and the heads on at least some of them.
Just curious, but why would it hurt to use the paper gaskets onder the valley pan today like what the factory did?

As far as hurting goes, you could get mis-alignment as a result of too much space between the manifold and head.

The new Fel-Pro sets I've bought had a thin paper gasket to go between the head and the tin pan.I use the tin over and over without paper and have never had a problem.I use RTV on the ends and have used the tin as much as 6 times on the hot rod.

As far as Ford not offering a replacement gasket, that could be because Ford decided that using sealer would suffice in place of the gasket. Maybe it does, but that doesn't mean that using the paper gasket is not as good
or better. I personally have a 1973 original 351C that has never been disassembled and I'll be willing to make a bet that it has the paper gaskets under the intake along with the valley pan.
Factory original oriented replacement parts and gaskets are more desireable than junk that is missing something. Good Parts and gasket manufacturing companies will provide as close to or better than factory original gaskets in order to maintain their customer base.
In other words, if it was on there originally they make it for people like me and I buy them. Always have and always will.
