skyman, there are alot of variable you dont see. for one youre comparing your heads to others. there are big differences such as runner lenght, volume, chamber design, etc. im not saying you cant make power with 202 valves but they generaly lose low end power.
as for big cams, these are not big cams. lift is just a small part of a cams job. the ex266 is a good small cam. nothing says that you will definately get more power with one cam as apposed to another.
