Intake Manifold Question

-
Does anyone know if I can use a beer can aluminum to block the heat riser passage?

You can, but it too will burn through. I blocked mine off with some roof flashing, and when I changed the intake, it had burnt through.

Interesting. There would be no point then. Someone suggested dog food can lid...but I don't have a dog :(
 
One thing to consider. I have the 1406 with the air gap. It does not come with a choke. Are you using one? I do not and it it fine. Just have to let it warm for an extra minute or two.

You can go with electric choke if you need it...
 
Sorry to revive this dead thread but I need to install my intake again. Did a whole front end rebuild and cam swap.

Get the proper gasket with the block off...

If you use the wrong material, it will burn through...

Even with the right material it may also if not installed correctly...

We put an engine on a dyno with one exhaust crossover flange gasket torqued properly, and one that wasn't... The one that wasn't torqued properly burned through, the one that was didn't... That proved that you had to have the joint tightened properly for the gasket to survive that heat/environment, even with the proper material...

I would use steel and not aluminum especially beer can. Very thin!
 
Do I cover both the middle port and the upper arch or just the middle port?

The outside U-shaped part doesn't go anywhere. You can block it, but it won't make any difference. The inner small port is where the exhaust flows thru.
 
All done. I put a piece of stainless in there. I guess I will report back if your guys instructions were bad and I have a leak. You guys provide a warranty right!?!
 
Thanks. Why does that U shape area even exist then?
Expansion relief for that particularly hot area of that head surface; the rest of that surface is relatively cooler. An interesting engineering problem... I wonder how long they had known about that problem when they designed these castings.
 
It's as good as what you paid for it.... LOL
Let's not get into "as good as what I paid". The only thing I haven't touched on this car is the back seat. And I bought it because it didn't need much work! Silly me. I love the car but I wish I had the experience I do know. Would have saved myself $3k on the asking price.

Thanks for all the help. I will let you guys know when I get it fired up. Will be a week or two still.
 
This Thread is just what I needed to know. I see that the Mopar intake manifold comes with two rectangular, stainless plates that should be placed on the head side of the gasket with high temp silicone to block the heat. I wonder if they need to be formed to fit inside the port on the head or just laid flat on the port. I'd think that just laying them flat might deform the gasket and create a gap that would leak exhaust.

Not from my exerience...if you're using composite intake gaskets, the shims will just embed themselves in the gasket material, but I would still throw a little gasket sealer around the area for extra insurance.

YMMV......
