Introducing our expertly engineered heads for Mercury V6 2.5L engines. These heads feature removable pucks to select an infinite range of compression in just a few minutes. They also feature a 1/8” npt gauge port for accurate temperatures. We recommend using NGK BR9EIX spark plugs.
Our new design now weighs 3lbs less than our previous version!
These heads fit 2.5L blocks with the 280 bolt pattern.
