I work for World. If you need anything, please don't hesitate to call.
If you want an honest opinion, CNC BLOCKS, HINK, CARL, whatever he is now is not the place to look. He is selective in his information and sometimes straight out inaccurate.
Rather than drone on here's a link:

We were the first ones to make aftermarket BBC blocks. Our MERLIN PRO was deemed illegal as an unfair advantage by the rules committee so we discontinued it.
We make a damn fine product no matter what CNCBLOCKS wants to make up.
My direct phone number is 201-403-3699 if you want to call me.
