On a set of Airflow heads for the street there is an option of either 66cc combustion chamber of 76cc. What does this mean, which is better and will it effect performance? The worst thing that could be done is to purchase something then regret it later because you didn't ask all the right questions. Thanks

the numbers give you the size of the combustion chambers,the smaller the number the more compression the motor will have.it does effect the combustion process[flame front,etc.].if you plan to go to forced induction the 66cc would not be a good canidate.the bigger the cc # the less compression the motor will have.
note;this is with using the standard piston and rod
