I posted this over in 5.0 Tech but didn't really get any input so I decided to post it here, it might actually belong in 5.0 Talk anyway
Anyway, I currently have GT40x heads and was thinking about getting some AFR 165's this fall. My question is, would I be better off just having my GT40x's heavily ported?
