No sir = We have been to the tear down barn a dozen times
Heads are carefully CC in the runners intake/exhaust as well
as valve removed and visually inspected by tech men who are
usually engine builders and or machinists or Both!
We do flow/inspect many heads to find the best ones. You would
be surprised how much these old casting vary from one to another.
We have 100 plus sets of heads on the shelf.
