G'day Ray,

Like all Packard flathead engines of that era Packard head nuts are tightened to 63 Ft Lbs. Might be a little late but, if not, they should be tightened down in the recommended sequence and in increments to "sneak up" on the 63. Then, after initial start up, allow to run until the engine is thoroughly warmed up(30mins) then retighten, again in sequence, to 63. Retighten again after say a couple of hundred miles, then check and retighten every year thereafter. Others may have a slightly different procedure that they follow for this important process.
