It is true that most aftermarket valves out of the box flow a little less than the oem valve but that doesn't mean you can't cut a valve to flow equal or better. In very high HP applications the OEM valve isn't gonna cut it.

Agreed, My reply was directed to vtecmasta85 and i doubt that with a statement like "It's not very hard to do" he is gonna go all the way to cutting valves.

I'm using supertech with a 30 degree face and I can tell that backcut actually does something. I dont have flow numbers, but I'm goin to continue to use ST valves. Skunk 2 valves are also ok to use.
