as many of you know the 03 piston domes are different than the late 04 on up design. which design is better for performance? the 7.3s used the pointed domes like the 03 6.0s. i noticed they went back to that dome on the 6.4s as well.
ford says the design changed for emissions purposes and to make the engine quieter. the only thing i see having an effect on emissions is the camshaft change they made.
