As part of the TR6 tuning process, Chip has sent an old TR6 head out to be cut down slightly and flowed.  Once he swaps the head onto the motor, he can report the difference on the dyno between the old and new.  We’ll have the exact specs for the new head so everyone can evaluate it to see if it’s worth it for their particular situation.  Pics of the head as it came back from the machine shop.

The machine shop reported some nice improvement on the flow bench, so we’ll see what it gets us at the wheels.
