230/250/292 exhaust manifold dimension question

[Prowbar]

Hello,

I'm looking for some dimensions from a Chevy/GMC inline 6 exhaust manifold. I've added a picture with the required dimensions.

The dimensions can be taken with the manifold still on. The dimensions are needed to get an approximate figure of the size of one of these manifolds.

I'm looking to possibly retrofit one of these manifolds to another six cylinder engine as these are still available.

Thanks in advance.

Is there someone with a 230/250/292 that is willing to take the measurements? Please do. Thanks.

Do you still need this information?
I have one I can measure.

Hello Jethro, thanks, but I happen to already have the measurements from elsewhere.
