stock for stock the vortecs are the better head. if your looking for a budget head that can make decent power they are the way to go. just be careful with spending too much on machine work to get them rebuilt and up to par. if you plan to run a healthy cam you need to change valve springs use screw in studs etc. also dont forget to factor in the price of a new intake and valve covers. sometimes it comes out cheaper to just spend more in the first place on a nice set of performance heads. dart iron eagles or something similar are excellent heads and by the time you factor in all the costs of using vortec heads sometimes you can get a lot more head for the same money.
