FYI - I'm running the P heads and trap 102 mph. This is with just a little port work. They're not the best flowing heads, but for the money they aren't bad at all(and they do flow significantly better than stock heads). They have smaller valves than most of the aftermarket stuff and have relocated spark-plug angles for better burn. The relocated spark-plug angle requires the use special headers, so that's a negative. Overall they're a pretty decent and affordable street head. Just my 02.
