How to fix a cracked block, easy also

Man I wish I knew about stich weld I threw a bunch of big $$$ motors out, easy also just takes a few hours.
Drill the ends of the cracks first, drill and taper for the tap, special. put them the first set in and grind flush then drill in between and insert new plugs. Put he next set in so they meet the first plugs. Wow works great
