There is a TON of info out there regarding this - Porsche explored the limits of head temps and thermal efficiency in boosted apps with the 935 cars, eventually going to water cooled heads which carried into the 962s. And yes, these track cars were always tuned on the rich side to aid in keeping head temps down - it's not fuel per se that cools the head, but it is the cooler combustion temp of the rich mixture.
