Depends, I'm using Hooker supercomps, had to ding 'em to get them to clear steering box and shock towers then a little grinding at the collectors to clear the AOD, which you shouldn't have a problem with. They do produce a little more low end over the hedmans I had on before which didn't take any beatings or grinding to fit. Both brands can be ceramic coated with the Hookers costing quite a bit more. I'm running a 347, if I was going with just the 302, I would use the Tri Y's, they have been around for a long time and have been proven to work well. I'm sure you will get plenty of opinions on this.
