No ones arguing that W type heads aren't better.
The point was, before TF's the average guy had ootb Edelbrocks to make high 400 hp power then TF allowed them to make 500+ hp now if some made like a mass produced like a 330 cfm version then the average dude could step it up to 600 hp with ootb heads.
Not say the heads shouldn't be checked or there's not better alternatives etc.. but most average guys are stuck at TF level right now.
That was the point nothing more.
