No, that would not go well. Your manifold ports would not align with the head ports. Those manifolds are mated at the factory, no two sets are exactly the same.
I might shave off a bit from the mating surfaces where the manifolds bolt together, just enough to match the thickness of your new block off plate and gasket.
Can you cut a round piece of steel that fits inside the exhaust manifold? An internal heat shield?

Interesting there hasn't been much discussion about this. when I did a search, most block off discussions are related to the 2f which, seem to have less of an issue w fitment.

 

[Tomba]

No first hand experience but that don’t look right, do you need the gaskets?

Someone will chime in…

No. I have the gaskets and block off plate but, sandwiched together results in this misalignment.... . I think shaving it down a bit is the proper solution as @Pighead suggested.

Need more pics, is that plate for when you use a header

No, this will be used for a stock setup....The difference in height is about 3mm or just shy of 1/8"

2 gaskets and a block off plate results in this. Is the best work around to shave a bit off the intake or Dremel out the ears to make a fit?

Sadness...

Why again are you doing this? That flap should be open when hot, What’s the problem

 

[Tomba]

The heat from he exhaust can crack the Alu intake. Hoping to avoid this.

Not a bad idea. Perhaps just cut down the full blockplate to fit inside the space that is in the bottom of the intake.

I like the sound of that, trim to fit inside gasket

My understanding is that the flap closes when hot, to keep hot exhaust off the bottom of the intake.

Am I wrong?

 

[Tomba]

You are correct. I am attempting to replicate that w the plate.

Other way around Sweet Pea

Well at least we got that right now I guess Iam thinking Chevy , Thanks for the info

 

[Tomba]

Gonna dive back in this weekend and see if I can put this manifold issue to rest .

 

[Tomba]

High hopes for a lil project completion today. All was going well but then I stripped one of the vertical manifold bolts.
Wasn't up for a another trip to the auto parts store for a tap. To be continued

 

[greenbeast]

That does suck…

 

[Tomba]

For sure and its anyone's guess how many times that thing has been removed/ reinstalled. As we all know there's always something that goes sideways...
