I just recently purchased trickflow 185's and my question is this. I have a friend that's doing a similar build and he's going with 210cc victor jr's. I selected the trickflows on the advice of darell and because they will fit my stock bottom end until I can afford the 347. I'm happy with the heads. My question is that my friend constantly says the victor jr's are amazingly better heads and that I'm loosing as much as half a second by running trick flows. I don't see how this could be true. How much better are victor jr's if any? Also he's going 331 and I'm going 347.
