Trickflow 190 r heads Street port vs Comp. port

[shabbyblue]

I have been trying to figure this out. What is the difference between the 2 heads the trickflow 190 street port heads and trickflow comp port heads? The comp ports cost more, but is there a difference? They seemed to flow the same. I'm building a street car with a 331 and a tmoss port/welded GT-40 intake. I'm wondering which one be better.

For you, basic street car, street port... you'll never notice the difference in the two
