I'm installing a Ford Autolite 4100 on a ECZ-B intake which for those not familiar with that manifold, has raised flanges, not a completely flat surface. Bought a Mr Gasket (?) #55 gasket. Fitting it, found the venturie holes are too big & it's very likely going to leak vacuum & or fuel. Anybody know of a gasket make with a bit smaller holes? I found someone with a 60s Mustang on the internet that had the same issue, but no positive solution was offered..   Thanks
