Brad 8 vs Brad 5 heads

I'm thinking of switching to a set of 8's non X, what is different I know I will need intake spacer, and different exhaust push rods, will my headers work? Are they much better flow / HP wise is it worth the upgrade? Thanks

 

your headers wont work most likely there have been a few sets of headers I have run by that will but very rare. There is some advantage to the change, all depends on what you are doing with them and what other changes you have made to what you are currently using..
