I am trying to understand a couple of things.

The A engine seems to be built like a tank, and 5.5 or 6:1 compression is low-compression in almost every other sense than the A engine. Why worry about 1 less thread into the block? Has anyone actually busted a head by not having the studs all teh way in?

Why should studs be tight in the block? As far as I know, when a stud or bolt goes into a threaded hole, the entire force of the connection is contained in 3 or 4 threads. Is the theory that making teh stud tight moves those 3 or 4 theads deeper into teh bolck?
