The heads arriving. I have already run these on my old nitrous setup, so more pics to come when they are cleaned up again. The Dart Pro1 LS3 heads are excellent to start with, but even these great heads picked up nearly 3 MPH in the 1/8 mile when Frankenstein reworked them. Amazing.

They were never flowed. I don't know if Frankenstein has flow numbers for this head program or not, I would have to ask.
