Heat Cross-over

i think with an aluminum intake you will get enough heat transfer to do the job it will just take a little longer. on my performer i jammed a ball of aluminum foil in the crossover on each side and topped it off with some high temp epoxy. it can easily be removed. it drives fine. weve been getting temps in the upper 90s and broke 100 more than once and i think if i had the crossover i would be having issues.
