I guess I made a mistake. These are supposed to be tried and true tips but I've never tried a grill block, fuel heater or hydrogen injection. I just think they would be worth doing based on what I've read. Here's my updated list of modifications.
Top 5 modifications:
1) Warm air intake
2) Remove engine driven cooling fan if equipped, replace with an electric fan.
3) Use low viscosity synthetic engine oil.
4) Retard the camshaft(s) a few degrees. This may require ignition and fuel mixture adjusments. Note that if the timing belt is old, the valve timing may already be retarded. Tightening the timing belt tensioner (if not self adjusting) will retard it a little more. If the distributor is driven by the camshaft, the ignition timing may become retarded. Advance it at least to specifications to get better fuel economy and power. If it is advanced too far, the engine may knock during acceleration. Note that retarding the camshaft will reduce low speed power but it may increase power at high RPM. If you have slow acceleration you might not want to do this.
5) Optimize the ignition timing, including centrifugal and vacuum advance curves.
