Slant 6 1bbl

I gave the dimensions right off a 1bbl intake. Why someone would dimension the bolt holes that are at a 45 degree from each other with a 90 degree dimension is unknown. The slant intake bolts are 2.95" on center probably 3.00" to any 2 bolt gasket. 1.70" bore? Just cut one from some gasket material. For a 2 bolt on carb. Just slot the holes, nothing any of us hotrodders have not already done for Mopars.
