Usually I wouldn't recommend them over AFR 205 or TFS 215, but where those heads really earn the salt is their flow velocity through smaller intake runners. They really shine over stock casting ported heads in the lower rpms b/c of their low end torque/throttle response. Up top they are still better, but the margin is much closer. Sinve you have a high-stalled a4, throttle response and oommph down low ain't gonna be an issue.

Save that extra $1000 + towards the rear and get both heads and a rear! Or a ported FAST setup?

BTW, what rear ratio are you running right now?

My car has the LS6 intake. Is the FAST setup HP/TQ gain worth the money in your opinion?
