Had some time to check fit on a head. No wobbles or ill fitment. Phew! Also compared to a Clifford. Over 1/4" deeper at the minimum on the inside and atleast .100 wider inside. More measurements will be made.
There is still no way to clear the huge block of aluminum that a Harlan Sharp rocker presents. The front and rear rockers will still need rounded on the pushrod side. Good news is my brand rockers fit without issue.
Getting a bunch of heads ready to machine, had a busy weekend. Setting up a new shop, family and my real job keep me very busy. Otherwise the VC machining jig would have been made.
