[QUOTE="TcM-668, post: 76569, member: 2854"] From the SVT Welcome Package: "High-Output 5.4L DOHC V8 Powers 2000 SVT Cobra R" Page 2 from middle down. Ed Olin "Cobra R's specially designed 4-valve cylinder heads are the key to it's power." "Intially we used the DOHC heads that were designed for Ford's Rough riders off-road truck racing program" "Intial development was a success, but because of tooling limitations, we had to design new heads for the cobra R. They're similar to the 4.6 cobra heads, but with a lot more flow through the intake and exhaust ports." "the engineers achieved this(improved airflow) by reshaping the intake and exhaust ports, redesigning the intake and exhaust valve heads and increasing the exhaust valve diameter by 2mm compared with the 4.6-liter engine." I guess I will plan on building up a running engine, and pull the '00 R motor since I don't want to wait til it breaks and have to jump thru hoops. besides, if I drop a valve, I don't want a patched head to run with... time to call Pauls HP and Sean Hyland and see whats out there.... Thanks again guys... Don... [/QUOTE]
