I want to keep my old HEMI healthy & happy. For most old cars I figure if the valve recession problem ever happens it probably needed to be gone through anyway but in your case with that low mileage I wouldn't risk it. The stuff, at worst, won't hurt anything and at best will keep that motor happy for another 200k. I'd spend the money if I had something that nice.
