Trick Flow small block heads

Any good reason Trick Flow and even Brodix limit the intake port to 190cc? Sure seems like a guy could use a little more like the 210-220 Chevies...on a race engine that is.


To put that another way as port volume goes up so does the need for a bigger valve to take advantage of more area. Some pistons wound need possibly some valve notch enlargement and mopar guys would be-itch that they weren't bolt on ready heads.
