It is not really a gallons of gas to use when breaking in an a fresh rebuild.   What is required upon the first start and run is keeping the RPM up to 2500-3000(RPM)  for 15-20 minutes so the camshaft can break in properly.  After that it is a matter of driving 500-1000 miles(1600 km) to allow the piston rings to seat in the cylinder bores.
