Just wondering is this is possible.. to melt expensive aluminum heads..

What sort of engine conditions would need to be present for it to occur? Has it happened to anyone?

The melting temp of aluminum is over 1200F I believe); in any case it's much higher than your engine could go to actually melt them.

Now leaning out a blown or nitrous motor can melt pistons (the ring grooves anyway from personal experience) but I would guess the temps skyrocket under those conditions.

They will melt from extreme cases of detonation.

I would be more concerned over warping the heads than melting them. However, detonation is hell on any part...pistons included.

Well, I saw chunks of an aluminum combustion chamber laying on the track after a Nitro Coupe pass...
