Low compression ratios, less than huge intake porting, and 'mild cams' all get covered up by boost pressure in the manifold. Rather than opposed to having manifold vacuum to pull in the air from atmospheric pressure, the manifold is filled and ready to blow into the cylinder the moment the valve opens. Not when the piston draws the vacuum. The piston just needs to get out of the way when there is boost in the manifold. I hope this answers your query.

The low lift cams on a flathead is still a restrictor if you are using a Mccullough or Paxton with 4-5lb boost.
