Dude, Mugen is on crack if he thinks the LS block is stronger than the GSR Block...
Look at the casting on the outside of the blocks...You see how the GSR has Vertical and Horizontal Casting Pattern in it...That design adds lots of strength to walls like a Rebar of sorts...
The GSR also includes a Main Cap Girdle that adds rigidity to the main bearing portion of the block...
There are many reasons why the DOHC 1.8 Vtec Blocks are superior to the DOHC 1.8 NonVtec Blocks...
Maybe you just misunderstood what Mr. Mugen said...
