Block girdles, yay or nay

Can a non splayed 4 bolt cap be used? Wouldn't it be a good idea to have the block align honed and have the entire assembly balanced? One thing that I've never seen on here is having the crankshaft checked for being straight, maybe because that's second nature to you guys. I read earlier on this post about using aluminium main caps? I don't think that is a good idea.

No. 4 bolt caps on a production block are unwise. Gain nothing, and can even effect negatively.
I ran the dog poop out of a 2 bolt X block for years at healthy power levels( X block also came in 4 bolt variety and has the meat to do so) unlike a production block.
