I always thought that the block girdle was designed to keep the bearings at an even wear rate. Fair enough, the block girdle might help, but both b20s i seen blow up had
block girdles installed still ended up cracking a sleeve. I have photos of the bore on these b20's when they were built and from the pixels you can tell the bore is not evenly round
throughout.... the b20 i had installed in my integra had the bore evenly round and thick throughout the whole circumference, i guess honda is not perfect.
