Rocker gaps?
Spark plug gaps?
and the age old question, retorque when and hot or cold?

Standard for tappets is 12 thou, set cold.
Plugs 25 thou.
Re torque the head after a heat cycle or two when cold.

With unleaded fuel - set the exhausts to 15 thou clearance. Plugs 28/30 thou. And yes I would retorque the head to 45 ft lbf after the first heat cycle.

Thanks. I thought I had seen somewhere about using a bigger gap for the exhaust valves.

Do not forget the rocker shaft pedastals 25lbs/ft and tighten in the correct sequence
