The power you will gain is minimal compared to the abuse you will put that stock head thru- make sure you have taken advantage of all the safe ways to gain power first- remember built block does not = built head- I have a type R head and I never rev past 8400 rpm and I bought it new from acura so I knew it was in great condition- IMO it just not worth the risk for a few hp my car made 330 whp at 10.5 pounds of boost reving to 8200 it is daily driven for two years now- this year I am doing a full build and uping boost

good luck w/ any choices you decide
