Help me upgrade clutches in my REPU, rotary GLC and FB

[Jeff20B]

Please offer your input to help me make some decisions, please.

'74 REPU mild ports with Atkins Camden 5" SC going on in a month
'78 GLC with 6 port 13B conversion going in soon
'81 FB with mild ported 12A (with plans for an NA 20B!!)

I have some parts here that I'd like to use. Tell me what you think:

I have two Racing Beat light steel flywheels (13 pounds)
One 8 pound super light steel flywheel (you can't get these new anymore) it weighs and drives about the same as aluminum, so think of it as an aluminum flywheel.

Various stock 215mm and 225mm clutch discs

One Street Strip 225mm pressure plate and one Street strip 215mm pressure plate plus various 215mm and 225mm stock pressure plates.

Ok, we know the more torque the engine produces, the larger the disc required. Or we can increase the clamping force of the pressure plate at the expense of your left leg and clutch hydraulics (or get a dual disc but that is $$$$). I have enough parts here so I won't need to buy anything. I just need help figuring out where each component should go.

The intended use of the vehicle is also important when choosing a clutch. The heavier the vehical, typically the stronger the clutch. For example the REPU came stock with a 225mm disc, but it had a funny step making it incompatible with any other model. I feel I should try to keep 225mm for the REPU if possible.
