They both make good valves. Some prefer a Ferrea, REV or Manley it is all in who likes what. This is more of personal preference question. You can change angles on either valve to make one "better" than the other.
One thing Brian is forgetting to mention is this test was done over a year ago (2/04) not yesterday. Much like he, us and every other cylinder head company, changes have been made to improve our product. Our newer 4.8/5.3 heads have a different port and chamber than they did when that test was done.
This post is not to start a fight or pissing match but just to give more insight to that test.

What type of PP head was in the test?What was the conditions?Was this engine dyno or chassis dyno?

BTW, REV probably has the best exhaust valve, and Ferrea or Manley for the intake, we use the stock exhaust on alot of heads because it flows as much as the aftermarket exhaust valves and cost alot less money.
EDC, would you like to look at our new intake ports? I could send you something if you like.

Brian Tooley Brian, when are you going to tell us what the Hell is going on down there. Akron is to tires as bowling green is to TEA. Charlie won't tell all. last I heard,your wife was abducted by the Summitt Mafia and this is a ransom payment. The other ones were good too. Good luck down there.

That's funny, word has it they are feeding her well, I get to visit her a few hours a week. Lots of work, developing around 8 different fully CNC ported heads, programming 3 CNC's instead of the 1, etc. I would like to send you a PM.
