let a professional do it on a truck as new as yours. yes it will have some performance gains but would be better with more mods in my opinion. its not so much the polishing that does the work but the porting. polishing is just to make it look good. if you do some research you will find that polishing in lots of cases wont add any more power then just porting. now porting with a rough finish will give you some roughness so the air doesnt get lazy and mix better as its going into the cylinder. but leave out this mod till you have a motor that is built to actually use it.
