I finally got some time tonight so I went ahead and took out my dermal drill and started notching the cylinder walls. It’s not a hard job to do but takes lots of patience and a steady hand. I had to swap a few sanding stones to get the botom side done so for the opposite side I will have to pickup some more sanding stones or a carbide bit to finish it off. My only suggestion is make sure you are wearing some protective glasses as metal shavings fly everywhere and also if possible wear a nose mask or a respirator.
Picture on the left is the un-notched block and the one on the right is notched.

im going to do a d16z6 turbo build and ive been doin some research and my question is why does the block need to be notched?
The reason i notched the block is because the I-Beam Connecting rods that i used from FJDistributors are wider and little bit thicker so this needs to be done in order to clear the cylinders on the bottom end.
