Some thoughts to put in you tool box (most you should already have).

-thermal coatings of piston top, combustion chamber, valve tops, exhaust port.
-check you fan speed against you rpm limit, do not want it to caveate.
-get the oil cooler off the motor and divert that air to the cylinders.
-Porsche seemed concerned w the exhaust valve cooling and added additional oil flow to them.
-use Nickie's instead of factory cylinders.

I think you are building a small displacement motor (under 2.5 with very high rpm). If you are not going much 400hp and do not over-spin the cooling fan should be ok. Using the above thoughts should be ok through 500hp+ on the track if you can keep the heads on the motor and the rods from turning into mush.

Good luck.
