Had a SBC rebuild there. Had to replace the head gaskets because no one noticed 8 water passages where blocked by this head gasket. The new Felpro gaskets have them. AND on a second trip to his shop, the son drilled and tapped a starter bolt hole in this same engine.All while talking smack about other shops breaking the ear off the block, he drilled the hole in the wrong spot. You can physically see its off just with your eye's. Avoid at any expense. Waste of time and money.
