What kind of pistons are used in a Duratec engine?
Flat-top pistons with a slight dome are used without valve reliefs in the older 3.0L Duratec engines that do not have variable valve timing, but pistons with four valve reliefs are required for additional valve clearance in the newer versions with VVT. The compression ratio is the same, so the newer pistons can be used in the older applications.
