I just finished my 2.7lt type 4 running a scat crank, carillo rods and chevy forged pistons. The compression ratio is 13:1. Will a normal type1 cooling system be enough or do I need to go for a porsche type setup when running with 102 octane fuel?

My previous engine ran on 100% menthanol, the menthanol helped with the cooling so I was able to drive the car without any fan housing.
