They're 2.5L heads and they were also deshrouded around the valves. I was told by Vadim that the 3.0 valves really don't fit, but I know that people have fit them. Another shop owner who specializes in head porting told me that the smaller valves will create higher velocity, which would be more beneficial than a large, but slow moving, amount of air. That particular guy ports 32V Cobra heads, and was porting a set of Cougar heads at the time I called him.
