5 BTDC degrees for unleaded on a DJ and disconnect the vacuum advance and retard and block hoses to time.

'''HarryMann''' said.. Valve seats are hardened but CR is high at 10.5:1 so it's just a matter of Octane rating and pinking/detonation. Dropping the static advance back about 5 degrees will just reduce performance a bit, but engine will run fine!
