Call and ask if they drilled the head deck holes into the water jackets...
According to the text........
" Cylinder Head Holes: Blind tapped to prevent leaks 1.400" thread depth "
I'd say nope.
I had a World Block, not aluminum mind you, and they were drilled into the water jacket and there is no reason to...What a mess. Called them, and they are worse than Indy for customer service. No thanks, never again. Oooh wait, it says they aren't drilled thru on the internet....
Every after market block has issues. Some are easy fixes, some are not. Customer service then comes into play, and they are horrible.
Bill Mitchell customer service blows.
Have a iron world wedge block with paper thin cracks in webbing above mains on drivers side.
I contacted Bill Mitchell and was told they have NEVER had a casting flaw / blem issue. And if there was a bad block it would have been scraped.
I ground out paper thin webbing until I found solid material. Still it was only .040ish thick.
Now I have 3 quarter size windows on drivers side above mains.
Looks like a LS block with bay to bay breathing!!
