Have had this engine apart for a few months now, busy with work, holidays, and hurricanes.
What’s the best way to clean these heads and valves? I was thinking of just buying a large container of cleaner and then placing each head and their removed valves in a tight container and letting it all soak for a week or more. But the cleaner is like $35/jug at Wal-Mart. Would it be more cost-effective to soak everything in kerosene, or some other solvent?
