Are these heads noted for cracking? I have a head that has a cracked that leaked water back into the cylinder which led it to be Hydro locked. The #4 block cylinder will need to be sleaved, but can the head be repaired? When looking into the Exhaust port the crack can be seen. Water will leak into the cylinder and when the exhaust valve opens, water runs into the cylinder.
What the heck happened?


It cost, WHAT? Dam!
