318 pistons to bring compression up

stumblinhorse said
So why don’t the kb399’s get mentioned to raise compression?

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.
