I'd say at minimum:
New filter (3 screws to remove - easy)
Check the band adjustment - easy

The pressure releif spring has lost some tension over the last almost 50 years so a couple turns out on it is good. Check both band adjustments with the pan off. Re-fill with type-f fluid. Other than that a 727 is really overkill for a mild 383 and no mods would do much for performance.

set the gap under the two levers just like you would valve lash. kunkel has me set my circle track 904 to 1/4 and 5/16 (I forgot which band was which/dont have the note in front of me right now). As said you might want to adj the hex screw (see what the guys say). new filter new gasket pan rails straight especially the perimeter around the pan holes. Any screws going into aluminum its a good plan to lube em but they should be wet with trans fluid as is but I'd check. I'd use some non hardening gasket cement (permatex #2) on the pan bolts to help keep em snug (not a dealbreaker but one of my idiosynchrosies (sp)

You could decide to replace the throttle pressure shaft, gear-selector shaft and oilfillertube seals. X2, VG plan (perfect time to do it) EDIT IF you are comfortable with taking out the VB which is the best way to access the big seal

How about a pan drain plug and check the pan mounting bolt threads in the tranny case. I had some that were stripped so I opted to have them fixed with heli-coils.

The MP is the absolute worst choice for a "kit", nothing there that you can't duplicate for free and minimal improvement.
