let me add a H. Sonata is the same long block ,,,has the same pistons and cam timing.
The Mitsu Diamante has higher compression pistons and different cams shafts. It also has a stronger block casting.
For getting some heads to rebuild latter Chrysler , like 91 0n , that had roller rocker arms are the same heads ( except they have stamped cam gears).
Happy hunting <img src="/forums/images/graemlins/cheers.gif" alt="" />
