I need to know the stock specs of the head so my machinist knows how much we can deck. It's not listed on the AERA system and I don't know the history of the head, if it's a virgin or not. i'd like to know before I go too far with it.
I gave him the only 2 #'s on the head, one is a part #, ends in AB, always a Ford part number indication. The other is, Q6PHA, which I assume is a casting number, but it's not in the system.
Also need those specs to double check the valve specs to have them 3 angled.
