I'm not sure about anything. :-)  I looked thru the receipts from the 
machine shop and couldn't find anything. I do remember I was a bit shocked 
when the machine shop told me how much was removed. I did ask about the 
possibility of piston - valve collision. And whether I would need shorter 
pushrods.

It is a 1500 block and head. In fact Joe, I think it's the block I bought 
from you. Maybe I can figure a way to measure the head while on the engine, 
any ideas ?
