Paging Wizeass
MSU? You might be closer if you said MTI. Now you are talking about port shape and velocity. You are very correct that cross section and flow for an NA combo are completely irrelevant when talking about boosted combos. A head for a NA combo will loose a lot of flow numbers when shaping the port for boost. Pressurize the air on the bench and see how it picks up.
Mikey is saying, and has been saying for awhile that stock heads are just as good for boost as anything. As usual this is just dumb.

Sounds like you should have went Forced Induction that way you won't have to wait on anyone to race your car. Mikey go buy a copy of HP tuners have the shop load the Nitrous and NA tune files on your laptop that way you don't have to wait for anyone. just switch the tunes your self. Makes sense to me.

Verdad Gallardo What you fail to comprehend in your "mathimatical" equation are a few things such as Boyle's Gas Law and adiabatic efficiency, which you blatantly disregard. This is really, REALLY basic stuff, so I would suggest you do some research before you come up with anymore bogus "mathimatical" equations. Try Corky Bell, for starters, since he explains this specifically.
I will ATTEMPT to explain this for the slow people (Mikey) aka Stewie.
Lets use engine dyno numbers for this example since those are real numbers.
(1) 370 cubic inch motor makes 500 na with stock heads.
(2) Same motor makes 750 with 7lbs of boost
(3) Add some heads ported by Nix (had to Brandon) to the NA combo and it adds 80 at the crank for a total of 580
(4) Same amount of boost will now make 820.
Now, please explain to me how heads dont make as big of a difference on a boosted motor please.

LOL, well I'm guessing that you assume since 7psi is half of what ambient air pressure is (at sea level BTW), you assume that an additional 7psi of boost is an automatic 50% power gain.
