I have Whipple 2.3 on my forged 5.0 Stroker and I am having my Heads Ported. I am staying with the stock valves. How do you think MPG will be effected with the ported heads? Mpg is not a strong concern but I am just wondering. Thanks

It'll go down I'm sure since you'll be using a little more gas all the time now instead of just during boost.

But I wouldn't expect a huge drop I guess.
