The gasket inner diameter is pretty much always larger than the bore. It is the cylinder wall that is the source of shrouding once lift gets the valve head at and past the gasket. Rather than using the gasket, I use the cylinder bore to scribe the never exceed diameter on the head.

You guys that think this way are totally wrong when talking about a head like a small block Mopar Speedmaster or Edelbrock head. I try to share what I learn but if you want to be a cement head, help yourself. All heads are not alike, and all chambers are different animals.
