You'll be lucky to notice it. And some of the information is in the coil Techinfo article to give you an idea of how different they are.
The 'standard coil' is shared by:
1992.5 (and all L67'* of that year), through 1996, ALL Bonnevilles, L27, L36, and L67 alike, as well as 1997 and newer L36'*.
The 'slightly hotter coil' appeared in 1997, the first year of the L67 GTP. All L67'* from 1997 and newer have this coil.
You might feel a slightly smoother idle and a BARELY perceptible improvement in power delivery (smoothness) through the midrange pull. I'm basing this on what I noticed (barely) switching to the MSD 8224 coil, which is slightly hotter than the 97 and newer L67 coil.
