As Pete noted above. The closer the valve is located to the cylinder bore the easier it is for a crack to materialize. Thus the earlier block is not really a wise choice for a performance build. If or maybe I should write when the engine is built for performance and ends up overheating or goes lean you will now have cracks. With an additional .125 overbore the possibility has now been increased. Care must be taken to keep the engine cool.
