Thanks for the quick response...what does a 67 or 68cc chamber do to our compression? Im going to call my machinist in the AM but curious what others are running with aftermarket heads. Trying to understand what the compression diff would be opposed to stock combustion chamber.

Smaller chamber = larger compression.
