Question about porting GT40x heads?

[caseywan]

I currently have GT40x heads and was thinking about getting some AFR 165's this winter. My question is, would I be better off just having my GT40x's heavily ported?

Keep the X heads and port them.. you would be amazed on the small diff between the X and the 165's on the engine ( other than price..) dont get lost in numbers or names..

Just me................................
