So, just to throw some water on this, does anyone know how the TF270's compare against either the Indy -1 or 325 heads? I can tell you from a flow bench perspective, these top out around 380cfm, and the B1 heads go +420cfm....
TF advertises 350-ish, IIRC
Comparing it to a B1 is a bit apples to oranges, given the B1 requires special pistons, etc., whereas the TF is basically a bolt on.
