Little more than you think. 
Not to mention make rather big gains on stock vs stock on gt30+ size turbos.

[sm=dontgetit.gif]so 25whp or so gain for swapping completly stock heads over pretty much the entire boost curve isnt good enough for you? Swap in a largeport aftermarket intake manfold and you see another 20-40whp on top of that. Guess that isnt to impressive either 
*gains vary with size of turbos.

Not to impressed with the first one. There was virtually no gain on the exhaust side which will offsetmost of the gains on the intake side. I wouldnt have guessed that impressive of a gain with the aeb head thou.

You got 25hp out of the port job in the first chart? No other changes other than tuning.
