He made 375 horse power at the rear wheels some where between 2900-3200 rmp. Cant rember exact whould have to ask him. That proves that you dont need wind this thing up reall tight just to make streetable power. Now he has a comp cam 292h whith 3500 stall and it his proabaly makeing somewhere between 425-435 rear wheel horse power and it will proably never see 7,800 rpm.
The point I was trying to make is you will give up a lot of torque by running the 4v heads.
