2.3 quad four

i have four 2.3 quad four . I race a ovall track exhaust gets red hot and keep blowing them up 9.5--1 and 10--1 piston motors

i dont get it ? is this a question?

This must be a riddle. Need better cooling and a shorter exhaust and/or lower exhaust temps. Also oil cooler a must for oval track. Those aren't the answer to the riddle but are good suggestions to avoid blowing up.
