Slant 6 1bbl

Why are you worrying about the smaller holes? You're not using the BBS, right? You're wanting to use the Holley Sniper, correct? You should use the style gasket the Holley Sniper needs, not the BBS. None of this is going to go together without you having to mod, fab and make something here and there. If that's what you thing or are trying to do, you need another hobby.
I just want a gasket for a slant to compare to auto light 1100 to see if the bore and the studs are the same . Im mentioning the stock style gaskets because the carter b&b which I wanted to keep to replace no one had one , no one sells them or a exact replacement for one . Why I temporarily put the adapter to the 318 style 2bbl . Which I love the power but can not run a air cleaner because the hood won't close. So I've come to where now I'd like to try the Holley efi kit . But it will only work if I can bolt it to the stock intake with no riser or adapter . And we still don't know the
Dimensions Are the same or different or how different they may be. Yes I want a near exact bolt on replacement . If it doesn't fit that's fine.
