There are a few different schools of thought when it comes to choosing between flat top and dish pistons for your engine. Some people believe that flat top pistons are better because they offer more compression, while others prefer dish pistons because they offer less compression and more airflow into the cylinders. Ultimately, it comes down to personal preference and what you want to get out of your engine. If you're looking for more power, then flat top pistons may be the way to go. However, if you're looking for better fuel economy or less engine noise, then dish pistons may be a better option.
