Just wanted to be sure you had the chamfer on the rods faced the right way. Sometimes if the pistons get installed wrong on the rods people turn the rods not understanding that there is a right and wrong way.
Seen a lot of crazy things in engines over the years.
As for
oil restrictors if you are not running a solid cam don't bother. Racers installed them to cut down on
oil to the valvetrain at higher speeds. If you are not racing don't bother.
Just my two cents.
