I would suggestion either the New Mallory ignition systems or the ICE Ignition Systems since the MSD folks have sent their stuff to China to be made.
Here is a link to the ICE Ignition which is the Best:

Regarding the fuel system, I would suggest Aeromotive:

Regarding oils, that depends on the clearances in the engines rods and mains.
