olds ebrock heads and street dominator intake question

[78_oldcruiser]

i keep hearing about ebrocks heads for the 403 and that you can only run ebrock intake on them... why is that? is there a magical switch or something that activates them together seriously though is this just something ebrock come up with to tell people so they would only buy ebrock or is it really true? i want to run a street dominator on them if i decide to get them

Port size is larger.
