15.5 cc.
The pistons are also lightened under the domes to minimal thickness.

Thanks John, just punched those numbers into big boyz calculator with the Hurricane heads having 95 cc chambers and it is coming up at 12.49 to 1 compression. Am I missing something ? Oh by the way this is for a 4.060 bore 4 5/8 stroke 120. Thanks   Josh

The several sets of Hurricane heads I've had my hands on came in at 97 - 99 cc.

Thanks John, That got it to 12.1 to 1 using 98cc's. Thinking the 12 to 1 pistons and an S&S 640 might be a nice set up with the hurricane heads. I'm at 2000' above sea level, CCP would be 199 .
