Best pistons currently available for 4.2 XK engine

Putting these in my motor,$950aud.Made by SRP a subsiduary of JE,oddly SRP will tell you they don’t do Jaguar pistons,these are apparently made in short runs for an Australian distributor,I bought them through my engine builder.Forged from low expansion alloy so can run tighter clearances than normally associated with forged pistons,(2/2•5 thou) which my engine builder says will be quiet on start up.
