    Are all P/N KB 199 pistons compatible? I have an engine with 7 pistons with what I believe is a date code 04 and 1 piston with a date code of 12. The 1 piston date code 12 has valve reliefs, the other ones with a date code 04 do not have that.

    Asked by: clopie
    Yes, all of the KB199's would be the same.
