Dish Top
A Dish Top style piston will effectively lower your engine's compression ratio by removing material from the top of the piston in a circular, "dish" shape. They are primarily used in boosted (supercharged, turbocharged) applications where low to medium compression ratios are desired.
Flat Top
Flat top pistons are very similar in nature to stock pistons, running at medium compression ratios. Consequently, they work great in many applications and performance levels. Valve reliefs are designed with appropriate clearance to fit most types of standard and aftermarket heads.
Reverse Dome (SCJ/Kaase)
Similar to a dish piston, the goal of a Reverse Dome piston is to lower the compression ratio of your engine, making them great for boosted (supercharged, turbocharged) applications. They are designed in such a way as to match the profile and shape of most standard and aftermarket cylinder heads. (Designed Specifically for the SCJ and Kaase Cylinder Heads).
