Quick head gasket question

Isn't it true that when picking a head gasket, the compression volume of that gasket should be as low as possible (while still maintaining proper quench) in order to maximize compression? I'll give an example...

The Cometic 5751 is a 4.060 bore, .051 compressed thickness gasket. The actual compressed volume of this is 8.486. The Cometic 5317 is 4.130 bore, .040 compression thickness, and has a compression volume of 8.780.

The object is to find a gasket where your quench will be set properly while having your compression volume as low as possible to increase compression, correct?

Someone correct me if I'm wrong.

How are you getting these volumes?

Stated it on the Summit Racing website... I assume they got it from the manufacturer.

Even if you did pi(r)^2 x vol = volume, you come out with the same answer...

I believe your idea is correct, for what most people on here would like to achieve.
