4ag Big Vs Small Port

Do big port and small port 4age heads have the same size inlet valves?

 

If they do, would the air flow be any different between the two heads?

 

Just trying to work out which head/ cam combinations would work best.

 

thanks

Edited by Rolliac

seriously.... just stick with the smallport.

IMO, its the best of all the 4AGEs, and i've owned all different varieties (except blacktop 20V)
