Thank you for the info, Blair, and for going into some specifics on the TFS.

I’m not going to pretend I know cylinder heads like some of the guys on here but I myself have out of the box survivals, I believe they flow the same as an out of the box BBM. I’m under the impression that the TFS heads come CNCd out of the box. I believe the CNCd Survivals flow 360 cfm is there a reason why they don’t get bunched in in this conversation. Now when I got my Survivals there was no BBMs or TFS so at the time I had thought they were way ahead of what was out there.
Curious. This is for ONE head. What would happen if this head were paired with an "ordinary" MR head on the same engine?
