For drag racing and with methanol there is
rarely a problem with the heads getting too hot.
I can run 14:1 with just a barrel
change (soon).
Petrol based fuels with good octane, like C14plus
and C16
can run OK on 14:1 but the head temp goes up real fast
and then power goes down.
In general I would suggest the higher octane fuel on air cooled heads than the same
comp ratio with water cooled heads.
