E7TE vs THE WORLD. HOW DID YOUR FAVORITE HEADS DO? CHECK OUT THIS TEST WHERE WE COMPARED THE STOCK 5.0L FORD HEADS TO 9 OTHER AFTER MARKET HEADS. WHAT ARE HEADS WORTH ON A 333 STROKER SMALL BL,OCK FORD? HERE IN PART 2, THE HEADS FLOW MORE SO WE USED A BIGGER, BETTER TEST MOTOR. PLUS BETTER DATA DISPLAY!

It was interesting how even the HP numbers were considering the fairly large difference in port volumes. I will say that the TW head is deceiving in the fact that the port volume "appears" small. However with the relocated valve, the port is a bit shorter in length and that shows up as smaller, but the actual height and width measurements are quite comparable to the other heads. I was sure the Z304's would do better than they did just from the average of the flow numbers. I guess that's why we don't race flow benches!
Thanks Richard for all this work.

we dont race dynos either. But we need flow benches, dynos, and to re-check ourselves against 20 year old data!
