From what I've seen on tests both in magazines and on the internet, the TFTW and the AFR 165's run really close. Canfields can do well for street heads but the availability is REALLY SPOTTY. If you order these, be sure you can cancel payment easily. This is only what I've heard, not personal experience. TFTW may need clean up as they're kinda rough from what I've heard. The AFR's are CNC machined and well done I've heard. Check a lot of other sources, as I'm still in the research stage myself. I think I'll get the TFTW and get them ported for myself.
