...at what HP are these cracking at? Anyone know? Are they better than a girdled 109? This one has splayed 4 bolt caps and 14 bolt head holes. Good street motor? Thanks!

The stage 1 blocks got the bad rap for cracking between the freeze plugs, you shouldn't have any problem, FWIW I've beat the snot out of a 012 stage 1 block for 3 years w/ no issues at all concerning the block.
