How much fuel do you have? How fast do you want to spin the engine? Is this a DD? Do you have anything done to the head to keep it clamped with increased cylinder pressure?

With stock head bolts,a stock gasket and no o-rings I would reccomend anymore timing than 16.5 degrees.

Beyond that on a stock motor and your asking for early dismissal of your headgasket.

Right now its stock. But eventually its getting the plate probably taken out, 4 thousand springs, the usual. Right now I have to get the timing adressed because with almost 300 thousand miles the timing has slipped a little and when its cold due to the timing being retarded it runs rough and smokes.

Retarded timing will make it easier to start and run better in the cold.
