The A052 heads have 'Job 331' hammered into both of them and '25' hammered into one. They were given a valve job by Nunzi in 2000. I wonder if this was Nunzi's way of documenting the customer's units? The invoice did not reference the job number.
Does anyone else have a set of heads that were worked on by Nunzi, or that can verify this was his head hammering goin' on?
My late 72 TA also has A052 heads and also A052 waterpump
