The heads as cast as delivered were actually 70cc. After my mods they were 77cc. I had them milled .100"(yes you read that correctly) and they landed at 62cc.

I did not need the notches for clearance....those valves would free drop down the bores... barely, but they did clear. But when I added the notches to the bore fixture it made a HUGE difference in airflow
