Wow that’s a lot of cracking, a simple test is to get a can of carb cleaner and while the engine is running spray some carb cleaner at the intake manifold, if the engine revs rise when you spray the carb cleaner you have a leak. Simple test on the charging system is to put a volt meter on the battery and check the voltage with everything switched off you should be getting over 12 volts, turn on ignition voltage should drop, start engine you should be getting 14 volts at idle, rev to 5k rpm you should be getting between 14.5 and 15 volts.

The battery is 12.2v turned off.

14.2v at idle.

14.6v at 5k revs.

Sprayed carb cleaner on the manifolds with no increase in revs.
