What carb base gasket should I use? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I did not realize I would have to give a second thought to which base gasket to use with a Holley 4160 carburetor and the Weiand 8120 intake manifold, but now I see there are at least three choices.

This is what the intake looks like and the three base gaskets.

A. 108-10 one square hole

B. 108-18 two oval holes

C. 108-58 four round holes

Which one would you recommend and why? Please be kind I am honestly trying to learn something here as I honestly do not know the benefits or limits of each?
