Does anyone know anything about cracked aluminum heads, lets just say someone cooked an engine and I'm told the head was cracked. Is it possible to repair them successfully this guy took the engine to an engine re conditioner who rebuilt the engine and repaired the head by using the overlapping stud method. Now after the head was repaired should one be able to see where the repair was because we can't see any sign of any repair. http://i109.photobucket....oyotaCrownEngine007.jpg

Basically it is a process of drilling a hole and inserting a slightly oversize tapered
