Vinnie ,
the part i,m mostly concerned about is the very top of the small end of the rod and the very bottom of the big end of the rod .
I,ve seen these rods ground on in these 2 areas by people thinking they were going to balance them the way they balance rods for , lets just say a small block chevy . On buick nail heads that ruins the rods .
The area just above the rod journal ( where the rod starts to narrow ) is the correct place to do the balanceing procedeure . Thats where the factory grinds them which is ok .
As long as the very top and bottom look ok we,ll be good . I couldn,t tell from the photos from the way the rods are laying .
