318 pistons to bring compression up

Isn't the KB399 is a forged KB167?

There used to be TRW 11.5 domed pistons available for the 318. Gave around 10:1 with 340/360 heads and a Fel-Pro composition head gasket. Don't know if these are still available.

no a kb167 is a +5cc flat top and a kb399 is a -6.2cc dome. Everything else is the same. Both are Hypereutectic aluminum.
