I am doing a 292 rebuild.  The junkyard engine I purchased the heads were badly rusted, like the valves were seized in the bores.  No problem, I will use aluminum heads.  So, I pitched the cast iron heads.
I called John Mummert a few days back and told him I am ready to order my aluminum heads. 
His answer was, "I don't have any".
OK, when will you have some??
Don't know, I have no castings.
Have you ordered more castings?
No..
When are you going to order more castings?
Don't know..  He would not commit to any timing.

OK guys.  Whoever knows John well, can you help me build a fire under this one?  I know he is busy and I have no idea how much time and effort goes into a foundry pour.   I am totally dead in the water without those heads.  I can't be the only one in the country who needs a set of those heads.
