could also say 853.

just because it has a stock head casting number doesn't completely rule out the fact that they could've been pulled and worked.

edit: could also be on the driver's side, as the heads are interchangable.

what cam is in the car? i'd guess the heads are stock and probably have not been removed if it only makes 395 whp. that is ballpark for most any cam bigger than a 224 haha.
