Offenhauser Manifold with Edelbrock Carb

As i've had to use the levelleing plate in between my Offenhauser manifold and edelbrock carp I need longer bolts. Could someone tell me what size they are?
Next question, there appears to be two holes on the manifold at each corner of the carb. I presume these are for fitting of different type carbs. do these additional holes need a bolt putting in them?

not sure of the bolt sizes, but they, being american, will be some unf or unc size, ie not metric.
the second bolt holes are as you suspect for different carbs, they only need blanking if they allow air into the manifold directly.

In my humble it's worth getting long screws with a thread all the way up to the head. You can then cut the heads off, clean up the threads and make studs out of them. Use two nuts locked together to wind them into the manifold. Once done you have no more worries about stripped ali threads etc.

Back in the 60's there were Fish carbs, very effective on Mini's

No Problem!
I guess that your Edelbrock Carp is a type of "Metallic" Carp!
