I would like some feedback on the pros and cons on running a integrated head on a 250 six chevy motor. Will it fit on any of the 250 six motors ?? Does it flow better ? I have heard it is prone to crack...I have both heads and want to use the best one..I also have a 165 hp marine 250 six..Is the cam different ?? I wonder where they pick up the extra 15 hp ?????SCRAP
