Wiseco pistons and K1 rods

Has anybody used the protrue pistons and K1 h beam rods are they any good are the tolerances good?

For you turbo slant six fans out there (both of you!) they make them for the leaning tower of power, as well,(for the 225's ...) both cranks, forged and cast.

About a thousand dollars total, for both rods and pistons, but, it's good insurance...
