correct you are even when done properly the block still cracks because there isent enough meat to support a 1/2in stud that is another reason gm went with the uni bolt studded blocks

Not a bad idea. Are you having them build the complete engine?

does anybody have more details/pics of the girdle process?

I saw the pics from the board member who bought one from ZZP, it appears the process ends at least, with welding the deck closed and milling the deck.

does anybody know what it looks like under the deck?

I'm assuming there's a press fit ring that goes into the water jacket?

Some people believe they machine a plate to the exact size down to the thousands of an inch and press it into the block.

Some people believe they fill the block.

This is a common way people fill blocks.

diy filled b series block, with writeup, comments welcome - Honda-Tech

Only ZZP knows...
