Either way just use the one with the correct cfm for the build.
 
Engine size x Engine rpm x Engine VE
3456

Engine size is in cid.

RPM is the MAX rpm your carb will need to support. Don't lie to yourself here. It'll hurt your performance if you do.

Engine VE is Volumetric Efficiency. You'll need a dyno to find this.
Here are the common readings:
Stock smog are about .08
well built performance about .09
forced induction is 1.0-1.1 usually
 
What are the numbers on the mounting pad of the carb?
