I don't understand how, I don't drive it hard and never overheated. But luckily I am pulling the motor for MS manis, 530bbs, and 3" exhaust. My question is, how much will I gain port matching my heads with the manifolds. I'm sure it will flow better, but is it worth the extra 250? I don't track it much and like I stated earlier I don't drive it very hard on the streets. Thanks for any input
