Cracked block is a cracked block and a cracked head is a cracked head.
If I was trying to save a RAV head or something, I'd try the stitch plugging stuff. Drill, tap, plug, grind and repeat...
I tried to torch weld a crack once. Drilled a hole at the end of the crack, ground a groove along the crack, heated up with the torch and started welding. Everything was going fine till I noticed a crack was chasing my welding.
All the effort of block fill, steel main caps, align honing mains, and you can still only max bore to 4.250. Then praying you don't find rust pinholes in 30 year old castings with .040 or less wall thickness to concrete in places.
Motor Plate better but not the cure.
Get an IAII.
