This is what most folks experience with these guitars.

> "I would like suggestions on some drop in replacements for these...I would prefer to just replace both."

IMO:
L-495GL48/L-490GN36
OR
L-495GL48/L-450GN36

> "Also, do I need to make any other mods like pot values to accommodate these BL pickups?"

Pot values are subjective, but for these guitars with these pups, I recommend a change to 250K pots. IMO, you need to replace the cheap Asian pots anyway.
