Is it worth the expense?
 

I have a 434 sbc with a toilet bowl,it runs great but like everyone else you always want a little more.My question is I have a set of brodix track 2 heads on it with 205 valves,these heads are out of the box.Would it help if I had heads flowed,I am running team g intake.

Definately more info is needed, but flowing your heads only gives you the numbers they currently produce. Having them ported would definately make a difference, provided there is room in the ports to do what is needed, and the port layout supports the correct mods. Best thing you can do is contact some head porters and give them your details. They can tell you if you're combo will improve with port work or if new heads would be a better investment. Do your homework though, you're likely to get 50 different answers to the same question....
