340 Stroker Rotating Assembly

I am considering this modification. I found a set of econo W2 rockers that could allow me to fully relocate the pushrods in the heads. A bigger valve is also tempting especially if I can get a lot of benefit in the lift range for the cams I am looking at.
What made you go with a 2.08 vs a 2.055?

Coming from someone that has done this mod you can get over 330cfm without moving the pushrod
