If you are simply looking to get a set of heads from a 91-92 Vin L they are the same...
You can use a set of 93-95 heads but you will need both.. These heads went to a Roller Pivot design as opposed to the Pivot for 91-92 Vin 1( SC ) and 91-92 Vin L ( NA ) heads...
Part number 24500363 was used for the 91-92 Model years was the same between the NA and SC'd models
Part Number 24501418 was used from 93-95 and the same for both NA and SC
( With the exception of the 3800 Series II which was the redesigned motor, The series II heads will not work, GM built both the Vin L and new Vin K this year-1995)
It may be easier to locate a set of 93-95 heads at this point weather NA or SC'd..
If there is any more info you need please feel free to ask
