Talk with Tony at Mamo Motorsports. He does a lot of work with the TF's and he can definitely get ya what ya need. I was looking at them for my CTS-V. Definitely a good buy!

 

I ended up pulling the trigger on these. Getting them through TEA. Had them mill for a 64cc chamber and they will be putting there final touches on them as well. Can't wait to see what they do.

 

Bad ***!! The 370 im building is getting them too. Just out of the box though. I can't wait!!

 

Yea I'm pretty stoked they should be a work of art can't wait!

 

All Tea does is there priority valve job and that bumps flow about 6cfm as advertised as I remember, Mamo re shapes the chamber a little bit, so I'm told, to what I dunno. I'm sure it's worth it.

As for my experience my setup with 10*smaller intake/ex and cam made the same as my l92 headed 408 sorry it wasn't a very good comparison. Makes good torque early on but that could just be my combo.

 

I was gonna pull the trigger on a set of these but decided on the tfs 245 with the nitrous exhaust port
