[QUOTE=Dodge;2252508]Just a side note. Don't use a tap to clean up the head stud holes. Use a thread chaser.
The thread chaser will clean out the threads. The tap will cut material out of the stud holes.

D.I.Y. chaser... notch a fastener to resemble a pie missing one piece and it will clear the threads without damage.
