Edlebrock 9266 manifold gasket won't fit stock LA 340 intake

I picked up a Edlebrock rubber 9266 intake gasket
to ensure I don't have heat issues between the AVS 2 carb and my stock 73 340 intake manifold.
The wider spaced gasket holes are made for the edlebrock performer intake but there is room to punch new holes to line up with the narrower factory manifold/carb mounting holes, is that okay to mount it?

The second issue is the actual intake area into the manifold doesn't line up well, part of the gasket covers the intake manifold opening
And the center devide between the opening looks like it might not fully seal between the two intake chambers.
How much of an issue will this make ?
Is the another gasket out there that fits better that can do yhe job?

Thoughts are always appreciated
