FAQ
What makes the “Marine Big Bowl different?The larger re-entrant bowl helps manage heat and air/fuel mixing at higher boost and fueling rates compared to a stock automotive bowl, supporting cleaner combustion under load.
Do I need machine work for .020 over?Yes. A professional bore/hone to .020 over is required. Always verify clearances and ring gaps during assembly.
Are coatings or fly-cuts included?These pistons are supplied in a race configuration for 12-valve builds. If your cam/valve setup requires valve relief or specific coatings, confirm those needs with your builder before ordering.
What supporting mods are recommended?Head studs, correct head gasket thickness, proper injector sizing, upgraded turbocharger(s), and adequate fuel supply are strongly recommended for high-output builds.
