Detergent oil keeps the dirt suspended in the oil so the filter can remove it. Since a lot of flatheads never had oil filters non-detergent oils was what they used. If you don't have an oil filter, just use the modern oil and change in when it starts to get a little dirty rather than waiting until it's really dirty.
I saw a test done on 'Non Detergent' oil. They sent it off for a test and found that it had basically NO ADDITIVE PACKAGE. It was just straight base oil without any anti-wear additives. It's the absolutely worst oil to put in any engine... anywhere. NEVER use this stuff in anything.
