The permanent repair for the block or head would be to drill, tap, and install pins. The technique involves drilling holes in both ends of the crack to keep it from spreading, then drilling holes at various intervals along the length of the crack, installing overlapping pins to fill the crack, then peening over the pins with an air hammer to seal and blend the surface. Grinding the rough remains gives you a smooth finish. Either tapered pins or straight pins may be used.

Tapered pins pull themselves into a crack as they are tightened to provide a tight seal along the entire length of the pin. This occurs because the threads on both the tapered pin and hole have an interference fit. Sealer really isn't necessary, but may be used for added insurance. The holes for tapered pins must be carefully hand tapped with a tapered tap, and the pins hand tightened.

The machine shop operator I trade with has used this method for 45 years and he tells me there have been no returns.
