I have CC'd a C80E-N head at slightly more than 76 CC's for an unmilled example that has not been valve jobbed to death.
The C6AE-R is the same chamber except the chamber is extended straight out on one end while the CJ chamber has a radius.
Many of the published specs are minimum NHRA chamber numbers that some bozo has transplanted to his book or website. Those numbers are not what a unmilled head will have, they are the minimum legal for class racing. NHRA tries to control compression ratio to make class racing fair.
