Now you are speaking my language!!!
Many subtle differences.
Special clutch (same as an L88)
W31 only specific items below:
Balancer
KA special water pump pulley
Flat top pistons
#6 heads (the W31 #6 heads have with 2.007 intake 1.625 ex)
Camshaft
Valve springs (also for W30)
Intake
Carb
Ignition has special calibration
Breather OAI
This is by memory.... I must have missed a few differences.
