Main bolt conversion again

[Arnout]

Since I have never seen a 2uz in real life I have to ask this again. What is exactly the problem with the 2uz when you convert it to four or maybe even six bolts mains. What I heard is the extra bolts weaken the block but I have not exactly heard what's wrong with the side bolts. I can only get 1uz and 2uz blocks here in europe, the 2uz blocks are hard to get so I have never opened one up myself.
When the casting is exactly the same for the 1uz, 2uz and 3uz, why does the 2uz go weaker with the extra bolts? Anyone have real good detailed pictures of the problem area?

casting isnt the same fir the 2uz - the 2uz doesnt have bosses for the cross bolts

*** does make a divergent 4 bolt billet mains cap thou which looks good
