My 200 block was cracked when I bought it for £150 on standard bore

I had the cracks fully ground out then welded up and the block decked when it was long studded

I had all 10 studs done

Also I had the block drilled and tapped into cylinder number 3 for the main oil return as this is supposed to be a hot spot on the cossie block

Not sure of the truth in all this but FMS does this on all there builds for that very reason
