One Piece Design Allows for Maximum Cooling without having to replace the stock studs. Modquad Cool Heads have one of the largest water cavities produced, holding up to 35% more water than others.
Our new one-piece design has an open flow between chambers to equalize water pressure and increase water circulation–for improved cooling, added protection and horsepower. Our head uses stock studs that do not have to be changed.
The Modquad head comes complete with copper washers, acorn nuts and O-Rings. Machined from 6061 aluminum in the USA.
