ok i need to know if any one knows the diferance betwen these 2 head #

L-v52 5R

L-v52 2R

need to know asap they bouth come off of 84 z31 turbo

 

I don't think those are part numbers. The numbers were used somehow in the manufacturing process, but not as part numbers.

All of the heads from the vg30e engines in the 84-89 z cars are the same and interchangable, with the exception of the W series engine built late in the 89 production run. Turbo or N/A, they're all the same.

Maybe this will help... Save it, then magnify until you can read it.
