Ted: Would those be the nos heads that came out of Argentina? If so they are available from Dennis Carpenter in N.C. Apparently they are good quality castings, but unfortunately they use the smallest intake valves. However, John Mummert offers 1.84" diameter intakes for them, if anyone is interested. I seem to recall that possibly Doc Frohmader (?) said the decks were fairly thick on them, if so they may be suitable for milling down. However, I'm not sure of that last info.These are just the run of the mill later model castings. Not sure where they were originally cast but thought that these were cast in the U.S. Small valves and big chambers. Nothing fancy, just new old stock.
